Servo drives are a vital component of modern motion control, widely used in automated equipment such as industrial robots and CNC machining centers. Particularly, servo drives for controlling AC permanent magnet synchronous motors have become a hot research topic both domestically and internationally. Current AC servo drive designs commonly employ a three-loop control algorithm based on vector control for current, speed, and position. The rationality of the speed loop design plays a crucial role in the overall servo control system, especially in the performance of speed control.

In the speed closed-loop of servo drives, the accuracy of real-time motor rotor speed measurement is crucial for improving the dynamic and static characteristics of the speed loop. To achieve a balance between measurement accuracy and system cost, incremental optical encoders are generally used as speed sensors, with the corresponding common speed measurement method being the M/T speed measurement method. Although the M/T speed measurement method offers certain measurement accuracy and a wide measurement range, it has inherent drawbacks, including: 1) The need to detect at least one complete disc pulse within the speed measurement cycle, which limits the measurable low-speed rotation; 2) The two control system timers used for speed measurement are difficult to maintain strict synchronization, resulting in a lack of speed measurement accuracy in scenarios with significant speed changes. Therefore, traditional speed loop design approaches using this speed measurement method are challenging to enhance the speed following and control performance of servo drives.
