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。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台理与否,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。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环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/T测速法。M/T测速法虽然具有一定的测量精度和较宽的测量范围

Servo drivers are an important component of modern motion control and are widely used in automation equipment such as industrial robots and CNC machining centers. It has become a research hotspot both domestically and internationally as a servo driver applied to control AC permanent magnet synchronous motors. The current design of AC servo drives generally adopts vector control based current, speed, and position closed-loop control algorithms. The rationality of the speed closed-loop design in this algorithm plays a crucial role in the entire 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 crucial for improving the dynamic and static characteristics of the speed control of the speed loop. In order to find a balance between measurement accuracy and system cost, an incremental photoelectric encoder is generally used as the speed sensor, and the corresponding commonly used speed measurement method is the M/T speed measurement method. Although the M/T velocity measurement method has certain measurement accuracy and a wide measurement range
