STATE FEEDBACK CONTROL OF PMLSM DRIVE BY USING THE SVPWM TECHNIQUE
In this paper the optimal state feedback control design of permanent magnet linear synchronous motor (PMLSM) is proposed. The mathematical model of PMLSM is obtained and linearised by introducing a variable in to the model which will decouple the linear and non linear components which is used to get the linearised model. The discrete linear quadratic regulator is used to design the state feedback control by finding the optimal gain matrix. The linearised PMLSM equations are used to form the objective function by incorporating weighting matrices Q and R. The motor is controlled by conventional PI method and then by the proposed method. In each method the system behavior is studied and the results are compared to evaluate them.
