伺服驱动系统是一种以机械位置或角度作为控制对象的自动控制系统，例如数控机床等。伺服系统中的驱动电机要求具有响应速度快、定位准确、转动惯量（ 机电系统中的伺服电机的转动惯量较大，为了能够和丝杠等机械部件直接相连，也为了得到极高的响应速度，伺服电机有一种专门的小惯量电机。

伺服系统是数控机床的重要组成部分，是连接数控装置（计算机）和机床之间的关键桥梁，伺服系统的性能在很大程度上决定了数控机床的性能，如数控机床的定位精度、跟踪精度、最高移动速度等重要指标。

伺服驱动系统的组成：机电一体化的伺服控制系统的结构、类型繁多，但从自动控制理论的角度来分析，伺服控制系统一般包括控制器、功率放大、执行元件、机械部件等几部分。

Servo drive system is an automatic control system that takes mechanical position or angle as the control object, such as CNC machine tools. The driving motor in the servo system requires fast response speed, accurate positioning, and rotational inertia (the servo motor in the electromechanical system has a large rotational inertia. In order to be directly connected to mechanical components such as screws and achieve extremely high response speed, the servo motor has a specialized small inertia motor.

The servo system is an important component of CNC machine tools and a key bridge connecting CNC devices (computers) and machine tools. The performance of the servo system largely determines the performance of CNC machine tools, such as important indicators such as positioning accuracy, tracking accuracy, and maximum movement speed.

The composition of servo drive system: There are various structures and types of electromechanical integrated servo control systems, but from the perspective of automatic control theory, servo control systems generally include controllers, power amplifiers, execution components, mechanical components, and other parts.
