Abstract: This paper was designed and optimized the drive system of CNC gear measurement center permanent magnet synchronous motor. And it was analyzed the id = 0 current control method of vector control principle and method of speed measurement, also SVPWM and adaptive fuzzy PI control of speed loop were adopted in this article,compared with the traditional PI control, it was eliminated the steady-state error, improved the system response speed, reduced the overshoot, made the system have a good dynamic and static characteristics. The Matlab/Simulink Simulation and experiment showed that the motor can stably operate in low-speed and verified the feasibility of the drive system design.
