NON-LINEAR PID CONTROLLER USING GMDH AND GMDH WEIGHTING FACTOR DETERMINATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a non-linear PID controller capable of operating with a small capacity of memory.;SOLUTION: A non-linear PID controller (10A) comprises: a deviation arithmetic unit (12) for calculating a deviation between an output value and a target value of a non-linear system (100) to be controlled; a derivative arithmetic unit (14) for calculating a derivative value of the deviation; a GMHD-PID adjustment unit (16A) for calculating a proportional gain, integral gain, and derivative gain associated with PID control of the non-linear system from three values which are a target value, deviation, and derivative value on the basis of GMDH theory; and a PID control unit (18) for performing PID control on the non-linear system by the calculated proportional gain, integral gain, and derivative gain on the basis of the deviation.;COPYRIGHT: (C)2014,JPO&INPIT
