Abstract: This paper studies a design method for the stabilizing systems of a multivariable robust PI controller. A necessary condition that a robust PI controller exists is given,and static decoupling is discussed with regard to the PI controller. Finally,a helicopter flight control systems is designed by this method. A satisfactory result of imitation is illustrated.

Key words: robustness, multivariable control, decoupling
