Abstract :
This paper concerns a kind of high performance permanent magnet synchronous servo system. Based on analyzing the mathematical model and vector control theory of permanent magnet synchronous motor, a method is applied to design servo system, which makes the current of D axis equal to zero. The system uses FPGA and DSP as the control unit, which increase the computation ability, simplify the circuit and guarantee the system stability. After analyzing the key links of the permanent magnet synchronous servo system, we discuss how to realize multi-loop control system through programming. Finally, the experimental course and the testing results on the numerical control machine of the designed system are given, which are the evidences of system correctness and system feasibility.
