Abstract

PURPOSE: To enable the selection of suitable value without hunting and stable in the dynamic characteristics, by selecting the rate element only, in the system selecting the control parameters in response to the number of sets of the operation units, providing rate, integration and differential oprators.
CONSTITUTION: The output signal S2 of the oscillator 1 and the output signal U of the set use analog memory AM2 are inputted to the PID operation unit(rate, integration and differentiation unit) 3, and after the calculation of deviation, one is fed to the adjustment section of the operation unit 3 and another is fed to the multiplier 4. In the multiplier 4, multiplication is made with the gain selection signal from the gain selection signal generators SG1WSGn5, gain selection transfer T06, first order delay unit LAG7, and the rate constant Kp only is corrected with the number of sets of the operation units. The output of the multiplier 4 is added to the preceding section of the operator 4, and the rate constant only among the control parameters is selected to a optimum value and connected to the transfers T1WTn for adjusters. The analog memories AM1WAMn are connected to the transfers T1WTn. As a result, stable control system without hunting can be obtained over the entire system.
