State feedback integral control with ‘ intelligent’ integrators

Abstract Integral controllers designed for various state determined systems, which are subject to constant disturbances and large initial conditions, very often turn out to be unsatisfactory, The overshoot becomes large and the speed of response may not be fast enough even when optimum (in some sense) feedback gains are employed. One euro for such problems is the use of ‘ intelligent’ integral controllers. A scheme for synthesizing an ‘ intelligent ’ controller is given, and then it is applied to the case of a simple system, by which the superiority of the ‘ intelligent’ integral control becomes clear.
