Abstract: A new procedure is presented for the synthesis of linear multivariable system subjected to plant model perturbations. Multiplicative perturbation is used to model the plant uncertainty. The controller has been designed by taking the plant perturbations. Robust stability is achieved by integral feedforward compensation and control law was synthesized such that the controlled system would maintain the system performance and the tracking of the error signals with plant perturbations in the steady state. The procedure simultaneously ensures conditions for a variety of specific design goals such as 1) closed loop stability, 2) static decoupling with complete and arbitrary closed loop pole placement, and 3) dynamic decoupling. The compensation scheme is presented in the frequency domain.
Keywords: Model perturbations, Robust control, Feedforward compensation, and Multivariable control.
