Comparative Analysis of PI and PID Controller for PMSM with New Sliding Mode observer

ABSTRACT: This paper presents the new proportional-integral-derivative controller (PID) for speed, position and torque control of permanent magnet synchronous motor with space vector pulse width modulation and sliding mode observer. PID improves the performance which gives the estimated result of current back emf of the PMSM. PID controller seems to perform better for the expected output. The THD has been analyzed for speed, current and torque. The comparative result has been carried out including PI and PID controllers. MATLAB/SIMULINK software has been used for the simulation purpose
