Servo driver is an important part of modern motion control, which is widely used in industrial robots and CNC machining centers and other automation equipment. Especially, the servo driver used to control AC permanent magnet synchronous motor has become a research hotspot at home and abroad. Current, speed and position three closed-loop control algorithms based on vector control are widely used in AC servo driver design. Whether the speed closed-loop design in this algorithm is reasonable or not plays a key role in the whole servo control system, especially in the performance of speed control .

In the closed-loop speed of servo driver, the real-time speed measurement accuracy of motor rotor is very important to improve the dynamic and static characteristics of the speed control of the speed loop. In order to find the balance between the accuracy of satellite measurement and the cost of the system, incremental photoelectric encoder is generally used as the speed measurement sensor, and its corresponding common speed measurement method is M/T velocity measurement.

Although M/T tachometer has certain measuring accuracy and wide measuring range, it has its inherent defects, including :1) at least one complete code disk pulse must be detected in the measuring period, which limits the minimum measurable speed; 2) The timer switches of the two control systems used for speed measurement are difficult to keep strict synchronization, and the accuracy of speed measurement cannot be guaranteed in the measurement field with large speed changes. Therefore, it is difficult to improve the performance of servo driver speed following and control by using the traditional speed loop design method
