摘要
针对现有二维弹道修正引信滚转角控制方法存在模型依赖性强、工程可实现性差问题,提出了基于变结构控制的引信滚转角控制方法。该方法建立了描述二维弹道修正引信滚转角运动的状态空间描述,通过选取了切换平面以及合适的趋近律,设计了二维弹道修正引信滚转角的变结构控制器,同时保证了控制系统的稳定性,并显示出较强的抗干扰能力。理论分析与仿真验证表明,基于变结构控制的引信滚转角控制方法与传统的双闭环PID控制相比,控制系统对干扰具有强鲁棒性,且控制精度更高。
A method of roll angle control based on variable structure control was proposed for the roll angle control problem of two-dimensional trajectory correction fuze.This method established the state space description of the mathematical model of the linear motion dynamics of two-dimensional trajectory correction fuze.The variable structure control theory was used to select the switching plane and the appropriate convergence law.The motion of the system state was divided into reachable stage the sliding stage,variable structure controller was designed to ensure the stability of the system state in the reachable stage and the asymptotic stability in the sliding phase,which made the roll angle control system of fuzeshow strong anti-interference ability.Theoretical analysis and simulation results showed that the control system based on variable structure control was more robust than the traditional double closed-loop PID control,and the control precision was higher.
