MAX-4/11/03/128/08/1/1/00 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. The

current, speed and position three closed-loop control algorithm based on vector control is widely used in the

design of AC MAX-4/11/03/128/08/1/1/00 servo driver. 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.

MAX-4

In the speed closed-loop of servo driver, the real-time speed measurement accuracy of motor rotor is very

important to improve the dynamic and static characteristics of speed control of speed loop. In order to find the

balance between measurement accuracy and system cost, incremental photoelectric encoder is generally used

as the speed measurement sensor, and the corresponding speed measurement method is M/T. 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) It is difficult for the timer switches of the two control systems used for speed measurement 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 driver speed following and control by using the traditional speed loop design method
