Optimization of permanent magnet synchronous motor vector control system based on particle swarm optimization

For permanent magnet synchronous motor control system at this stage has defects such as the poor robustness and control, this paper proposes an optimization scheme of permanent magnet synchronous motor vector control system based on particle swarm optimization. Establish the mathematical model of the permanent magnet synchronous motor, use the particle swarm optimization algorithm to optimize the PID controller parameters of the system speed loop on the basis of the theoretical analysis of vector control, PID controller and particle swarm optimization, build the optimization simulation model of the permanent magnet synchronous motor vector control system based on particle swarm optimization in MATLAB/Simulink and conduct the related research. The simulation results show that the optimization scheme is effective and it can significantly improve system control performances. Copyright © 2014 Binary Information Press.
