2、med after its rotor permanent magnet excitation. Compared with the induction motor, permanent magnet synchronous motor does not need exciting current, the stator and rotor magnetic field is no relative movement, there is no slip loss. And permanent magnet brushless DC synchronous motor compared to A
3、C permanent magnet synchronous motor has less torque ripple, etc., it is more suitable for high precision and high performance occasions, especially in direct drive and low speed, the PMSM has better performance. Compared with ordinary stepper motors, permanent magnet synchronous motor control syste
4、m has a higher speed, more stable operating performance, and the batter position control. With the development of the control technology and magnetic materials technology, the sine wave composed of permanent magnet synchronous motor control system is becoming the mainstream of modern power transmiss
5、ion system. In the traditional control system design, the more good control system performance more needs to be controlled more accurate mathematical model of the object. However, in many production processes, in order to get a sufficient accuracy of both, but also to facilitate the analysis of cont
6、rol system model is very difficult. Fuzzy control is to summarize the experience of people, according to the control of the experience summed up the formation of control rules, the control rules to form a controller to replace the people in the complex production process control. With the advanced f
7、uzzy thinking to penetrate the traditional control areas for the development of control theory has opened up new directions, the fuzzy control provides a new design method. This paper analyzes the traditional PID control and fuzzy control features. In order to solve the parameters of PID controller
8、can not be changed with the actual running state of the system, design a fuzzy PID speed controller. And create a simulation model with MATLAB for the simulation and comparison. In the PID controller, the proportional part is to make the system tend to set the output value; the integral part is to i
9、mprove the system steady state performance and reduce steady state error; and the derivative part is reflected in the reduction for the overshoot. But the three control parts will interact, making the performance of other control decreased. In order to balance the role of the three control coefficie
10、nts, adding the fuzzy control of three tuning parameters. Fuzzy PID control system significantly reduced the overshoot and the rate of elimination of steady-state error is improved, the steady state ripple is also reduced. Performance of the system in general has improved, reflecting the advantages
