【英文介紹】
CB06551 PRD-B040SSIB-63 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 actuator used to control AC permanent magnet synchronous motor has become a research hotspot at home and abroad. The current, speed 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 the algorithm is reasonable or not plays a key role in the whole servo control system, especially in the performance of speed control. In the servo drive speed closed-loop, the real-time speed measurement accuracy of the motor rotor is very important to improve the dynamic and static characteristics of speed control of the speed loop. CB06551 PRD-B040SSIB-63 In order to seek the balance between measurement accuracy and system cost, incremental photoelectric encoder is generally used as the speed measurement sensor, and the corresponding common speed measurement method is M/T speed measurement. Although M/T velocity measurement method has a certain measurement accuracy and a wide measurement range, but this method has its inherent defects, mainly including :1) the speed measurement cycle must detect at least - a complete code pulse, limiting the minimum measurable speed; 2) The timer switches of the two control systems used for speed measurement are difficult to maintain 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 drive speed following and control by using the traditional speed loop design method
