Abstract: On the basis of the analysis of permanent magnet synchronous motor in the mathematical model and its vector control, studied the principle of permanent magnet synchronous motor rotor flux oriented control strategy, for the rotor flux oriented vector control technology critical issues rotor flux observation, the design of sliding mode rotor flux observer, sliding mode observer was presented based on the control system with Matlab / Simulink simulation, Simulation results show that the system has wide speed range, good dynamic and static performance.
Key words: permanent magnet synchronous motor; vector control; sliding mode flux observer
