Servo drive 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 drive used to control AC permanent magnet synchronous motor has become a research hotspot at home and abroad. The current, velocity and position three closed-loop control algorithms based on vector control are widely used in the design of AC servo drivers. 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 [1].
In the closed-loop speed of servo driver, the measurement accuracy of real-time motor rotor speed is very important to improve the dynamic and static characteristics of the speed control of the speed ring. In order to find the balance between measurement accuracy and system cost, incremental photoelectric encoder is generally used as the speed sensor, and its corresponding speed measurement method is M/T speed measurement. Although M/T velocity measurement method has certain measuring accuracy and wide measuring range, it has its inherent defects, including: 1) at least one complete code plate pulse must be detected in the speed measurement cycle, 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 occasions 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
