Research And Design On PMSM AC Servo Control System Based On DSP

PMSM AC servo system is one new-style AC servo system made up of PMSM , modern electronical technique and control technique.Because of its good performance,it has become one of research hotspots in electric drive of the time.In this thesis,Based on a digital signal processor TMS320F240,a controller for PMSM is researched an designed.we analyzes the mathematics model of PMSM,researchs vector control of PMSM and space vector PWM,discusses the controller of position , speed and current,designs the MRFAS position controller , PID speed controller and PID current controller,sets up PMSM AC servo control system, designs DSP controller ,and develop the corresponding sofeware.At last ,the designed controller is simulated under MATLAB/SIMULINK,and the results are gived.
