Abstract

PURPOSE: To reduce the number of searches and to remarkably decrease the search time, by corresponding one evaluation function to one parameter of control unit, searching three types of parameters independently parallelly, and altering the result at the same time.
CONSTITUTION: External disturbance D predetermined in pattern is fed to the control variable 2, the control deviation caused in the control unit 1 is integrated in timing until the designation time with the first, second, and third operation units 3a, 3b, 3c, and the intermediate variables E1, E2, E3 to calculate the evaluation function are obtained. The operation to obtain the variables E1WE3 is made by the integration equation specific to the unit. Next, E3 only is through the function generator 4 among the integrators E1WE3 and the evaluation functions F1, F2, F3 are operated at the fourth, fifth and sixth operators 5a, 5b, 5c. The parameter search units 6aW6c store the inputted functions F1WF3, compare them with the next inputs, and output the parameters KPO, TIO, TDO with sequential correction so that the result reaches minimum value. In the selection circuit 7, input is made according to the set of parameters KP.F1, TI.F2, TD.F3 to output the optimum values KP', TI', TD' to the display unit 8.
