摘要
船载脉冲雷达伺服系统为了提高跟踪和测角精度,驱动部分采用了多电机控制的方式来消除机械齿隙所造成的系统非线性影响。单速度环和速负反馈法、双速度环负反馈法、直接差速负反馈法是当前工程中常用的电机同步控制方式。通过对这三种方法的探讨,针对该型雷达伺服系统同步控制存在的不足,对该型雷达伺服系统的速度环设计进行了一些改进。
To improve the tracking and angulating precision, multi -motor control method is adopted to eliminate the nonlinear impact caused by the mechanical Backlash in serveo system of a ship - borne pulsed radar. There are three methods commonly used in the field to make the motors work synchronously, including the negative feedback of single - velocity - loop, the negative feedback of double - velocity - loop and the negative feedback of differential rotational speed. Methods to improve the velocity - loop are provided and discussed in order to solve the synchronization control problem in the servo system of the pulsed radar.
