Abstract

T h e aim of these paper is to realize a sensorless vector control scheme for a non - sa lient pole PMSM using a state observer of kind “Sliding Mode” for rotor flux position and speed estimation . The proposed scheme of SMO is simulated for different switching functions and the performance is compared during low speed operation which is a non - observable region . This scheme has greater accuracy than the conventional SMO and is simpler too. The PMSM parameters variations are compensated by means of SMO and the initial rotor position is not needed. The results taken from simulations in MATLAB/Simu link, validate the effectiveness of sensorless control system for PMSM with Sliding Mode Observer.
