本文论述了通过设置摩擦力矩观测器和引入前馈控制的方法,对精密转台中的摩擦力矩进行动态补偿,提高了转台精度井为研制结构简单而性能良好的新型转台提供了途径。
In this paper, the friction moment observer and the method of introducing feedforward control are introduced to dynamically compensate the friction moment in the precision turntable, which improves the precision of turntable and provides a way to develop a new turntable with simple structure and good performance.
