[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distributed constant type analog filter in which the characteristics of each element can be reversibly changed by externally operating the characteristics. The present invention relates to a cooperative method for performing adjustment.

In addition, the present invention relates to a cooperative system in which, for example, in a circuit having an element whose element value can be reversibly changed by an external operation, the characteristic is adjusted by an external operation while observing the characteristic.

[0003]

2. Description of the Related Art Conventionally, when an equivalent circuit to be adjusted is known and the correspondence between an adjustment amount of an adjustment unit and an element value in the equivalent circuit is known to be linear, adjustment before adjustment is performed. The element value of the equivalent circuit showing the same characteristic as the target and the element value of the equivalent circuit showing the same characteristic as the target characteristic of the adjustment are obtained, the difference between these element values is calculated, and the adjustment amount is calculated using a linear correspondence. There is known a method of performing adjustment by replacement.

Conventionally, the relationship between the operation of the adjustment unit to be adjusted and the change in the characteristic is regarded as linear in a minute operation, and the relationship between the adjustment amount and the change in the characteristic is expressed by a matrix, and the target value is calculated by matrix operation. A method is known in which an adjustment amount for approaching a target value is obtained from the difference between the measured value and the observed value to make adjustment.

A method using the matrix will be described.
In the method using a matrix, for example, when the adjustment target is a filter, an electronic circuit, or the like, as shown in FIG. 3, characteristic values 309 to 312 at specific frequencies 305 to 308 on the frequency characteristic 304 to be adjusted are converted into target characteristics 303. The characteristic values 309, 313, 314, and 312 at the specific frequency above
For example, focusing on a specific point on the waveform representing the characteristic, such as approaching the target value, the target value and the measured value are approached.
A point of interest such as the specific frequency is called an observation point, and a characteristic value at a certain observation point is called an observation value. In FIG. 3, reference numeral 301 denotes a frequency axis, and 302 denotes a characteristic value axis.

[0006] The matrix used in the method using the matrix is
It can be obtained by taking the inverse matrix of the matrix created from the unit change amount of the observation value at each observation point when each adjustment unit is sequentially changed minutely. At this time, from the condition of the inverse matrix operation, the matrix formed from the amount of change in the observed value when the adjustment unit is minutely changed must be a square matrix, and therefore, the number of observation points is Must be the same as the number.

For example, in an adjustment target having four adjustment units X ₁ , X ₂ , X ₃ , and X ₄ , four observation points P ₁ ,
When the adjustment is performed while focusing on P ₂ , P ₃ , and P ₄ , the adjustment point X
It is obtained by dividing the amount of change in the observed value at the observation point P _j (j = 1, 2, 3, 4) when _i (i = 1, 2, 3, 4) is slightly changed by Δx, respectively, by Δx. Assuming that a certain unit change amount is M _ij , X ₁ , X ₂ , X ₃ , and X ₄ are each represented by ΔX
_{1, ΔX 2, ΔX 3,} P 1 when changing only [Delta] X _4,
Changes ΔY ₁ , ΔY of observed values at P ₂ , P ₃ , P _4
2 , ΔY ₃ and ΔY ₄ can be approximately obtained by the following equations.

[0008]

(Equation 1)

Therefore, assuming that the difference between the target value and the observed value at the observation point is ΔY ₁ , ΔY ₂ , ΔY ₃ , ΔY ₄ , the adjustment amounts ΔX ₁ , ΔX ₂ , ΔX ₃ , ΔX ₄ are approximated by the following equations. Can be sought.

[0010]

(Equation 2)

In the adjustment method using a matrix, each adjustment point is minutely changed to obtain the unit change amount of the observed value, and the adjustment amount is calculated from the above equation to adjust the adjustment target. However, since the adjustment amount calculated by the above equation includes an error due to linear approximation, after the adjustment operation, the characteristics of the adjustment target are newly observed, and if the error with the target value is large, the newly observed observation value Is used to repeat the adjustment amount calculation and adjustment.

Further, as an extended system of the system using the matrix, a system in which the matrix is appropriately changed according to the characteristics of the observed value in the repetition of the adjustment amount calculation and the adjustment is described in the document "I.

[0013]

However, the method using an equivalent circuit is a method that can be applied only when a model of an equivalent circuit or the like to be adjusted is known, and thus has no versatility.

The method using a matrix is a method that can be applied even when a model such as an equivalent circuit is unknown. However, the number of observation points and adjustment units must be the same because of errors due to linear approximation of the object. The probability of successful adjustment is not high because there is no sufficient number of observation points due to the restriction that the number of observation points cannot be established, or the presence of inappropriate observation points, and the object to be adjusted must be operated before the adjustment is completed. Do

And information transmission means 111 for transmitting all information such as adjustment amount candidates, observation values, model elements, and target values among all connected devices. And

First, the operation of the operation device 110 to be adjusted will be described with reference to FIG. Before the adjustment operation, the adjustment target operation device 110 obtains a set of observation points of interest from each of the adjustment amount presentation devices 112 to 114 via the information transmission unit 111 (step 601). Before the adjustment operation, the target value calculating means 106 obtains target values for all the observation points,
A set of the observation point and the target value is transmitted to another adjustment amount presenting apparatus via the information transmitting means 111 (step 602).
Thereafter, the adjustment target operation device 110 sequentially repeats three states: an observation state (step 603), a model element creation state (step 605), and an operation state (step 606). If the observed values match the target values for all observation points (step 604), the adjustment is completed (step 60).

When the adjustment target operation device 110 is in the observation state, as shown in FIG. 7, the observation means 104 observes the characteristics of the adjustment target at all observation points obtained from the respective adjustment amount presentation devices 112 to 114 (step S1). 701), a set of observation points and observation values is transmitted to the adjustment amount presentation device via the information transmission means 111 (step 702).

When the operation device 110 to be adjusted is in a model element creation state, as shown in FIG.

The observation means 104 observes the characteristics of the adjustment targets at all observation points obtained from the respective adjustment amount presenting devices 112 to 114 for each of the minute operations and notifies the model element creation means 105 (step 803). The model element creating means 105 obtains the unit change amount of the characteristic at all the observation points for each of the finely operated adjustment points using the transmitted observation values, and obtains the finely operated adjustment point name and the unit change amount for the observation point and the unit. A model element is created as a set with the amount of change (step 80).
4) Adjustment amount presentation device 11 via information transmission means 111
The information is transmitted to 2-114 (step 805). After the micro operation, each adjustment point is returned to the position before the micro operation (step 806). If there is an adjustment point for which no model element has been created, the process returns to step 801.

To the operating means 103 (step 901). For example, each adjustment amount presentation device 112 to 11
The adjustment amount candidate transmitted by 4 is evaluated by an evaluation formula given depending on the adjustment target, and the adjustment amount having the best evaluation value is selected. Alternatively, for example, according to each adjustment amount candidate transmitted by each adjustment amount presentation device, the operation unit 103 actually operates the adjustment unit to be adjusted, observes the characteristic of the adjustment object by the observation unit 104, and operates the operation unit 103 before operating the adjustment unit. An operation of returning the adjustment unit to the state is performed, and an operation of comparing a target value with an observation value obtained when the adjustment unit is operated is performed, respectively, and an adjustment amount that obtains a measurement value closest to the target value is selected. The operation unit 103 operates the adjustment unit to be adjusted using the adjustment amount calculated by the arbitration unit 102 (Step 902).

Next, the operation of the adjustment amount presenting devices 112 to 114 will be described with reference to FIG. Before the adjustment operation, the adjustment amount presentation device transmits the set of observation points of interest to the adjustment target operation device 110 via the information transmission unit 111 (step 1001).

The adjustment amount calculation model creating means 108 creates an adjustment amount calculation model by performing an inverse operation (inverse matrix operation) of the target model (matrix) (step 1105), and transmits the adjustment amount calculation model to the adjustment amount calculation means 109.

When the adjustment amount presentation devices 112 to 114 are in the adjustment amount calculation state, as shown in FIG. 12, the adjustment amount calculation means 109 pays attention to the target value and the observed value obtained from the adjustment target operation device 110. Using only the observation points, the target value vector and the observation value vector are created by arranging them in the order of the observation points arranged at the time of creating the matrix (steps 1201 and 1202). Further, the difference between the created target value vector and the observed value vector is calculated, and an adjustment amount is obtained by a matrix operation with the adjustment amount calculation model transmitted from the adjustment amount calculation model creating means 108 (step 1203), and information is transmitted as an adjustment amount candidate. The information is transmitted to other adjustment amount presentation devices and the adjustment target operation device 110 via the means 111 (step 1).

Although the target value is calculated by the target value calculating means 106 before the adjustment operation, a similar target value may be given to the adjustment amount presentation devices 112 to 114 as a parameter in advance. In addition, the model element creation unit 105 operates to create a model element each time of adjustment, but when the adjustment operation starts,
As soon as the adjustment is advanced and the error of the model becomes large, the operation may be appropriately performed. Furthermore, the model element creation means 105 may be omitted, and the model element or the target model may be provided to the adjustment amount presentation devices 112 to 114 as parameters in advance.

An evaluation state (step 1405) is taken. The operation when the adjustment amount presentation device is in the adjustment amount calculation state is as described in the description of the embodiment of the first invention.
