METHOD FOR DESIGNING FEWER FACTORS CONTROLLER BASED ON LOOP SHAPING DESIGNING METHOD

摘要

PROBLEM TO BE SOLVED: To improve designing efficiency by systematically making the transmission function of a fewer factors controller.;SOLUTION: As for a controller designed based on a loop shaping designing method, similar conversion is performed by including a free parameter Φ indicating the degree of freedom, and an unobservable part is removed from the state space expression so that the controller can be made to have fewer factors. In this method, the free parameter Φ is generalized with a p-order multi-input and output controllable canonical form so that a conditional expression for making the controller to have fewer factors can be calculated, and an arbitrary parameter is selected by a genetic algorithm so that a controller 4 can be systematically made to have fewer factors.;COPYRIGHT: (C)2002,JPO
