Abstract

PURPOSE:To improve the plant control accuracy by controlling the feedback gain in accordance with the change of the state value of a controlled system and based on a dynamic characteristic model so that the polar arrangement is fixed for the response characteristics of the state value. CONSTITUTION:The state equation of a controlled system 10 is shown as x=A.x+B.u. The optimum feedback F/B again F which is set at an F/B block 11 is obtained by minimizing the evaluation function shown by A and B as well as the coefficient matrices Q and R. In this case, the F/B gain is controlled by an optimum F/B gain setting means 12 so that the polar arrangement is fixed for the response characteristics of the state value (x). Thus the optimum F/B gain F is obtained in a short time. Furthermore an error if caused between a dynamic characteristic model and the actual dynamic characteristics is corrected by an optimum F/B gain adaptive correction means 13.
