基于复合控制的舰载火箭炮伺服系统仿真

Simulation of Ship-borne Rocket Launcher Servo System Based on Compound Control

舰载武器受到海上风浪等因素的影响,会产生俯仰横滚等方向的运动,必然影响对目标打击精度。为提高海上舰载武器稳定精度,通过设计二阶线性自抗扰控制器,完成被控对象的速度控制闭环构建。将门控循环网络与PID控制相结合,实时控制伺服系统位置输出。仿真结果表明,线性自抗扰控制器和门控循环网络的引入抑制了海浪扰动对系统的影响,有效改善了系统的稳态特性。

Ship-borne weapon affected by wind and waves at sea will produce pitch and roll motion.The disturbance will inevitably affect the target striking precision.In order to improve the stability precision of Marine ship-borne weapon,a second-order linear active disturbance rejection control is designed to complete the speed control closed-loop construction of the controlled objects.And the gated recurrent network and PID control are combined to control the position output of the servo system in real time.The simulation results show that the introduction of LADRC and the gated recurrent network can restrain the influence of wave disturbance on the system and an improve the steady-state characteristic of the system effectively.
