چکیده

This paper addresses a robust integral control scheme for a class of nonlinear uncertain systems. Hence, disturbance rejection and set-point regulation are the main goals in the proposed method, and a state-feedback control design would be employed to satisfy the mentioned aims. Then, a linear matrix inequality (LMI) based procedure would be introduced to the controller synthesis. Consequently, a matrix transformation is presented to translate the controller design issue into an LMI feasibility checking problem. Thus, the controller’s gains are numerically calculated by a solution of LMI approach. To show the applicability of the method, the results are used in a numerical example. Comparing the disturbance attenuations and transient performance in none-zero regulation problem, the outcomes verify the efficiency of the proposed technique over the other method.
