Abstract: This paper deals with the sliding mode speed control(SMSC) of permanent magnet synchronous motor(PMSM). Sliding mode controller is an advanced technique to control the electrical Drive. By using this controlling technique, transient& steady state response can be improved compared with the conventional PI controller. In this paper, the rotor position of motor is tracked through outer speed loop and current through the inner current loop to control the PMSM. The entire SMC speed control of PMSM is designed in MATLAB (SIMULINK).
Keywords: SMSC, PMSM, MATLAB (SIMULINK), PI Controller.
