摘要：

The paper presents an approach to design a robust PI controller for an active suspension system with uncertain parameters. To take care of parametric uncertainty in the system, the transfer function of controlled system is modified in the interval plants by using the kharitonov's theorem of stability. The stability region of the system is found by plotting the (k(p), k(i)) - plane which is plotted using the stability boundary locus method. The parameters of the controller from the stability region are found using pole-placement method, which assure the better performance quality of the system by choosing one of the parameter like closed loop poles or relative damping or natural undamped frequency of the control response. The designed robust PI controller is realized using MATLAB Simulink.
