Abstract:

The control system of separately-controlled and variable frequency for the permanent magnet synchronous motor needs to be measured by the external device,thus increasing the difficulty of the design.A self-controlled and variable frequency speed regulation system for permanent magnet synchronous motor is studied.Self-controlled and variable frequency speed regulation systems can adjust the speed and allow the system to stabilize through position sensor to timely being feedback the speed information when the load is changing.The modeling and simulation of self-controlled and variable frequency speed regulation system for permanent magnet synchronous motor is described in detail based on Matlab/Simulink,and the simulation results are analyzed.The simulation results show that the self-controlled and variable frequency speed self-controlled and variable frequency speed regulation of control system for PMSM has good dynamic and static performance.
