AMCI 7264伺服驱动器是现代运动控制的重要组成部分，被广泛应用于工业机器人及数控加工中心等自动化设备中。尤其是应用于控制交流永磁同步电机的伺服驱动器已经成为国内外研究热点。当前交流伺服驱动器设计中普遍采用基于矢量控制的电流、速度、位置三闭环控制算法。该算法中速度闭环设计合理与否，对于整个伺服控制系统，特别是速度控制性能的发挥起到关键作用。

AMCI 7264在伺服驱动器速度闭环中，电机转子实时速度测量精度对于改善速度坏的转速控制动静态特性至关重要。为寻求测量精度与系统成本的平衡，一般采用增量式光电编码器作为测速传感器，与其对应的常用测速方法为M/测速法。M测速法里然具有一定的测量精度和较宽的测量范围，但这种方法有其固有的缺陷，主要包括:1)测速周期内检测到至少一个完整的码盘脉冲，限制了低可测转速;2)用于测速的2个控制系统定时器开关难以严格保持同步，在速度变化较大的测量场合中无法测速精度。因此应用该测速法的传统速度环设计方案难以提高伺服驱动器速度跟随与控制性能

AMCI 7264 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. In particular, the servo drive 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 this algorithm is reasonable or not plays a key role in the whole servo control system, especially in the performance of speed control.

AMCI 7264 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 the speed control. In order to find the balance between measurement accuracy and system cost, incremental photoelectric encoder is generally used as the speed measurement sensor, and its corresponding common speed measurement method is M/ speed measurement. M velocity measurement method, of course, has a certain measurement accuracy and a wide measurement range, but this method has its inherent defects, mainly including :1) the detection of at least one complete code pulse in the speed measurement cycle, limiting the low measurable speed; 2) The timer switches of the two control systems used for speed measurement are difficult to maintain strict synchronization, and the speed accuracy cannot be measured 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
