摘要
针对船用遥控武器站伺服控制系统在稳定、跟踪和射击时,受到平台摇摆、射击振动与冲击等因素的影响,该文设计了一种基于扩张状态观测器的伺服控制算法,实现伺服系统非线性因素的实时动态补偿,有效改善遥控武器站伺服系统的抗干扰性,提高跟踪与射击的精度。数字仿真结果表明,可有效提高伺服系统的稳定与跟踪精度,并通过设备实际验证,可满足遥控武器站的使用需求。
Aiming at the influence of ship swaying,shooting vibration and impact on the servo control system of shipborne remote controlled weapon station when it is stabilizing,tracking and shooting,a servo control algorithm based on extended state observer is designed to realize real-time dynamic compensation of nonlinear factors of the servo system,effectively improve the anti-interference of the remote controlled weapon station servo system,and improve the accuracy of tracking and shooting.The digital simulation results show that it can effectively improve the stability and tracking accuracy of the servo system,and can meet the requirements of remote controlled weapon station through the actual verification of the equipment.
