高精度机床用电机SGMGH-44A2C3B

 伺服（servomechanism）又称随动，是用来地跟随或复现某个的反馈控制。伺服使物体的位置、方位、状态等输出被控量能够跟随输入目标（或给定值）的任意变化的自动控制。它的主要任务是按控制命令的要求、对功率进行放大、变换与调控等处理，使驱动装置输出的力矩、速度和位置控制非常灵活方便。在很况下，伺服专指被控制量（的输出量）是机械位移或位移速度、加速度的反馈控制，其作用是使输出的机械位移（或转角）准确地跟踪输入的位移（或转角），其结构组成和其他形式的反馈控制没有原则上的区别。伺服初用于国防军工, 如火炮的控制, 船舰、飞机的自动驾驶,发射等,后来逐渐推广到国民经济的许多部门,如自动机床、无线跟踪控制等。

基本释义

伺服是指利用某一部件(如控制杆)的作用能使所处的状态到达或接近某一预定值,并能将所需状态(所需值)和实际状态加以比较,依照它们的差别(有时是这一差别的变化率)来调节控制部件的自动控制。
