SCHNEIDER C400A811110 伺服驱动器

伺服驱动器（servo drives）又称为“伺服控制器”、“伺服放大器”，是用来控制伺服电机的一种控制器，其作用类似于变频器作用于普通交流马达，属于伺服系统的一部分，主要应用于高精度的定位系统。一般是通过位置、速度和力矩三种方式对伺服电机进行控制，实现高精度的传动系统定位，是传动技术的高端产品。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

Servo drives, also known as "servo controllers" or "servo amplifiers," are a type of controller used to control servo motors. Their function is similar to that of a frequency converter acting on ordinary AC motors, and they are a part of servo systems. They are mainly used in high-precision positioning systems. Generally, servo motors are controlled through three methods: position, speed, and torque to achieve high-precision positioning of the transmission system. It is a high-end product of transmission technology. 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. Especially the servo driver used to control AC permanent magnet synchronous motors has become a research hotspot at home and abroad. 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 overall servo control system, especially in the performance of speed control
