ABSTRACT:
A high-performance feedback controller having both a target value followability and a disturbance suppression characteristic is provided, and its characteristic arrangement is as follows. In a feedback controller, which receives a target value r and a controlled variable y and supplies a manipulated variable u as a calculation output to a control object which has at least one input u as a manipulated variable and at least one output y as a controlled variable, a compensator G.sub.c (s), whose internal calculation arrangement is given by G.sub.c (s)=.alpha./{G.sub.n (0)-G.sub.n (s)} using a nominal model G.sub.n (s) as an approximate characteristic of the control object and an arbitrary positive parameter .alpha., performs a compensation of a comparison deviation (e=r-y) between the target value r and the controlled variable y.
