　　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/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，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

　　主流的伺服驱动器均采用数字信号处理器（DSP）作为控制核心，可以实现比较复杂的控制算法，实现数字化、网络化和智能化。功率器件普遍采用以智能功率模块（IPM）为核心设计的驱动电路,IPM内部集成了驱动电路,同时具有过电压、过电流、过热、欠压等故障检测保护电路,在主回路中还加入软启动电路,以减小启动过程对驱动器的冲击。功率驱动单先通过三相全桥整流电路对输入的三相电或者市电进行整流，得到相应的直流电。经过整流好的三相电或市电，再通过三相正弦PWM电压型逆变器变频来驱动三相永磁式同步交流伺服电机。功率驱动单元的整个过程可以简单的说就是AC-DC-AC的过程。整流单元（AC-DC）主要的拓扑电路是三相全桥不控整流电路。

　　随着伺服系统的大规模应用，伺服驱动器使用、伺服驱动器调试、伺服驱动器维修都是伺服驱动器在当今比较重要的技术课题，越来越多工控技术服务商对伺服驱动器进行了技术深层次研究。

　　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3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。

　　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 balance the measurement accuracy and system cost, the incremental photoelectric encoder is generally used as the speed sensor, and the corresponding common speed measurement method is m/t speed measurement method. Although m/t speed measurement method has certain measurement accuracy and wide measurement range, it has its inherent defects, mainly including: 1) at least one complete code disk 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 strictly synchronized, and the speed measurement accuracy cannot be guaranteed in the measurement occasions with large speed changes. Therefore, it is difficult to improve the speed following and control performance of the servo driver by using the traditional speed loop design scheme

　　The mainstream servo driver uses digital signal processor (DSP) as the control core, which can realize complex control algorithm, digitalization, networking and intelligence. The power devices generally adopt the drive circuit designed with the intelligent power module (IPM) as the core. The IPM has integrated the drive circuit, and has fault detection and protection circuits such as overvoltage, overcurrent, overheating and undervoltage. A soft start circuit is also added to the main circuit to reduce the impact of the starting process on the driver. The power drive unit first rectifies the input three-phase power or mains power through a three-phase full bridge rectifier circuit to obtain the corresponding DC power. After rectified three-phase power or mains power, the three-phase permanent magnet synchronous AC servo motor is driven by three-phase sinusoidal PWM voltage source inverter. The whole process of power drive unit can be simply described as AC-DC-AC process. The main topology circuit of the rectifier unit (AC-DC) is a three-phase full bridge uncontrolled rectifier circuit.

　　With the large-scale application of servo system, the use of servo driver, servo driver debugging and servo driver maintenance are all important technical issues of servo driver today. More and more industrial control technology service providers have conducted in-depth technical research on servo driver.

　　Servo driver is an important part of modern motion control. It is widely used in industrial robots, CNC machining centers and other automatic equipment. Especially, the servo driver used to control AC permanent magnet synchronous motor has become a research hotspot at home and abroad. At present, the current, speed and position closed-loop control algorithm based on vector control is widely used in the design of AC servo driver. Whether the closed-loop design of speed in the algorithm is reasonable or not plays a key role in the whole servo control system, especially in the performance of speed control.
