Annotation: On the practice in real systems the plant parameters, usually, are known not precisely or can change according to unforeknowable rules in specified limits. Such parameters are accepted to call interval parameters, and control systems – interval control systems. An approach to the robust controller synthesis maximizing interval system stability degree is suggested. The approach is based on coefficient estimations of stability indices, allowing interval systems stability degree maximization and estimate its lower bound.
