Abstract :
This paper presents the online identification method for interior permanent-magnet synchronous motor (IPMSM) drive system with the maximum torque per ampere (MTPA). The inductances of the motor are identified by recursive least square (RLS) method based on mathematical model, considering the flux saturation state. Using this technique, the improvement of the MTPA trajectory for IPMSM can be implemented along with the effect of magnetic flux. This final paper presents an idea and a procedure of the proposed algorithm. The simulation results are carried out and presented.
