Modeling simulation and analysis of closed loop speed control of PMSM drive system

摘要

This paper presents an advanced simulation model of Permanent Magnet Synchronous Motor (PMSM). The vector control scheme of a PMSM drive has been implemented using the developed simulation model. In the developed model, speed and torque as well as the voltages and currents of voltage source inverters components can be effectively monitored and analyzed. The developed simulation model has been implemented using Matlab and the dynamic response of PMSM drive has been analysed for constant speed, varying torque and variable speed constant torque operation. Also, the simulation results have been presented. The simulation results of the developed model has been validated with the circuit simulation using the PMSM block available in the Matlab/Simulink library. Therefore, it can be expected that the developed simulation model can be an easy to design tool for the design and development of PMSM drives for different control algorithms and topological variations with reduced computation time and memory size.
