This paper introduces an ac servo control system that uses permanent magnet synchronous motor (PMSM) as object of control. It combines the feature of permanent magnet synchronous motor and servo-control, and designs the fuzzy self-adaptive of PID controller to achieve control of the position loop, speed loop and current loop. The simulation results of Matlab7.9 show that the controller has an excellent controlling effect.

In this paper, the tricyclic control block diagram for CNC AC servo system of three phase permanent magnet synchronous motor was established. And three loop PID controller tuning was analyzed. At the same time, this paper proposed the tuning tricyclic PID parameters adopting GISE. Then take the CNC milling machine for example, simulation tuning was conducted in MATLAB using GISE. The results show that the servo system is no overshoot, fast response and good stability. So GISE is more suitable for parameter’s optimization and tuning of permanent magnet synchronous motors’ AC position servo system.

Permanent magnet synchronous motor (PMSM) AC servo system has the characteristics of uncertainty, time-varying, nonlinear and fractional order. Applying the traditional control method is difficult to achieve the desired control effect. The fuzzy control has strong adaptability to the parameter change, nonlinearity and imprecise model of the controlled object. The simulation model of permanent magnet synchronous motor three closed-loop systems is established. The control principle and the realization of space vector pulse width modulation (SVPWM) are studied by using a vector control strategy. Due to the fractional-order characteristic of the motor, a fuzzy logic algorithm is used to realize the parameter self-tuning of the fractional-order proportional integral differential (PID) controller. The controller is selected as the position regulator of the servo motor. It combines the precision of fractional-order PID controller with the adaptability of fuzzy control and adds feed-forward to improve the response speed. The path tracking experiments on several different paths are carried out, and the results show that the control method is effective and can meet the trajectory tracking requirements of servo control. Finally, the speed and position tracking test of the PMSM AC servo system is carried out on the test verification platform, which verifies the effectiveness of the control algorithm.

Power circuit is the core of high precision permanent magnet synchronous motor (PMSM) AC servo system. It is composed of three-phase AC-DC circuit and Intelligence Power Module (IPM). Three-phase AC electric currents flows through the major power circuit and changed to sinusoidal symmetrically AC currents to drive PMSM to work. For the high precision PMSM AC servo system, a design method of the system’s power circuit was given and the specific parameters of the circuit were calculated. According to the circuit, system simulation was carried on and simulation results show that the design of power circuit is feasible and the high precision PMSM AC servo system has good performances such as high position and trace accuracy, large range of adjustable speed, fast response and strong robustness. So the power circuit designed not only guarantee system’s robustness but also system’s following performance.
