Abstract :
For the high-performance and low-cost AC servo system, the electrocircuit and control software are designed in this paper. Combined with the arithmetic of vector control, the NC instruction is embedded in the control model. Also, the NC instruction, machine loop and current loop are successfully achieved in the same control circle, and the time of control circle is determined in the 60 us. The response frequency and the performance of motion control are improved greatly. The experiment results show that the control system can achieve good dynamic and static drive performances.
