Abstract

A robust H_infin optimal speed control scheme for a DC motor with parameters variations and disturbance torque using a linear matrix inequality (LMI) approach is presented in this paper, the stability and robust H_infin performance index of the linear uncertain system are analyzed. The simulation results show that the closed-loop system has asymptotical stability, strong interference suppression ability and optimum performance.
