Servo drives are an important part of modern motion control and are widely used in automation equipment such as industrial robots and CNC machining centers. In particular, the servo drive used to control the AC permanent magnet synchronous motor has become a research hotspot at home and abroad. The current, speed, and position 3 closed-loop control algorithms based on vector control are widely used in the design of current AC servo drives. Whether the speed closed-loop design in the algorithm is reasonable or not plays a key role in the performance of the entire servo control system, especially the speed control performance.
