Performance Improvement of permanent magnet synchronous motor

proposed in this research: The implementation of the speed control loop and the IT.Permanent Magnet Synchronous Motors (PMSMs) are widely applied in industrial and robotic applications due to their high efficiency, low inertia and high torque - to- volume ratio. So, due to the importance of PM synchronous motor in many categories, this research about improving its performance is proposed. Simulation for dynamic and static models for ac Surface Permanent Magnet Synchronous Motor (SPMSM) with the aid of MATLAB - Simulink environment is introduced. The modeling procedures are described and simulation results are presented. The dynamic model has the capability of predicting the machine’s behavior for this type. This non - linear model of the PMSM in d-q reference frame is defined. The dynamic model is developed by coupling electrical equations and mechanical equations of the PMSM. All simulation results are presented for all machine’s variable characteristics. The validity of dynamic model is checked by two ways: first using various frequencies values under constant Vlf manner; second with the aid of static characteristics by means of comparisons. After that, it proposes Surface Permanent Magnet Synchronous Motor (SPMSM) Control Strategies with Their Neural Network Regression Functions. Vector control of PMSNl allows for the implementation of several choices of control strategies while control over torque is retained. Each of these control strategies
