A study is made about the structure and its mathematical model of FT-PMM. The design of the vector control system (SVPWM) based on the id = 0 control strategy is proposed, which realizes the closed-loop vector control with feedback of speed, current, and position. This method is proved right by Matlab simulation. From a hardware level, the dsPIC30f4011 is used as the core of the system. With the help of the design of the bootstrap power supply of IR2110, the number of power is reduced and the cost is saved. The inverter circuit consists of 3 independent H bridges was used to control each wingding independently in order to enhance the ability of fault tolerance. Through hardware test, the result indicates that this vector control system could satisfy the demands of speed control and stable operation. After Man-made fault is set, the fault-tolerant performance is analyzed and the system is proved to have fault-tolerant capability to a certain extent.

The quality of high-speed machining workpiece is determined by drive control performance of motorized spindle. Vector control is one of high-speed motorized spindle control method, but the traditional controller is difficult to effectively overcome parameter disturbances caused by parameter variations from internal and external system. So it is necessary to use intelligent control. In this paper, a model of a speed and flux-closed-loop vector control system with an inner torque-closed loop is established, and a fuzzy controller is used to adjust the speed. MATLAB is used for load simulation of high-speed segment of motorized spindle, and then the simulation results show that high-speed motorized spindle can be increased in to the high-speed segment using a short period of time, and it has strong anti-interference ability and excellent performance at the same time in the control system presented in this paper.
