Sliding Mode Controller with DOBC and MTPA Trajectory for Surface-Mounted PMSM

This paper provides a new controller technique based on Sliding Mode Control (SMC) and disturbance observer- based control (DOBC) for surface-mounted permanent magnet synchronous motor (SPMSM). The paper considers the maximum torque per ampere (MTPA) trajectory as the control strategy. The proposed technique is applicable for non-linear servo systems such as SPMSM and is supposed to be the highly efficient control method. The MatLab Simulink model block diagram and simulation results are provided in the paper with further discussions. The comparison between proposed method and proportional-integral-derivative (PID) controller as conventional methods is also performed and indicated in the paper.
