Vector Control System

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.

In order to control the position, speed and current of the PMSM, six SVPWM signals are generated with the motor vector control method, and the vector control strategy with three closed loops is projected. According to the control principle, the circuits of the hardware modules are designed and built, and the program of the control process is compiled and downloaded the EMCU, and then the human-computer interaction interface of the system is implemented by LabVIEW. The results of the test show that the control system designed can control the rotating speed and the high-speed pendulum operation of PMSM precisely.
