Abstract :
A model based efficiency optimization algorithm for speed control of interior permanent magnet synchronous motor (IPMSM) drive is proposed in this paper. In order to optimize the efficiency the loss minimization algorithm is developed based on motor model and operating conditions. The d-axis armature current is utilized to minimize the losses of the IPMSM in a closed loop vector control environment. The complete simulation model for the closed loop vector control of IPMSM drive incorporating the proposed loss minimization algorithm is developed using Matlab/Simulink software. The effectiveness of the proposed algorithm is tested in simulation at different dynamic operating conditions. It is found for the results that the efficiency of the proposed IPMSM drive is improved significantly as compared to the conventional id=0 control technique.
