巡航导弹鲁棒轨迹线性化控制器设计

基于轨迹线性化控制方法研究了巡航导弹控制器的设计问题。考虑到系统建模误差和外界干扰等不确定因素对TLC控制器性能的影响,研究了鲁棒轨迹线性化控制方法,设计了相应的控制器,并采用Lyapunov方法严格证明了闭环系统所有误差信号一致最终有界。最后应用新控制方案设计了巡航导弹飞行控制系统,仿真结果表明了方法的有效性。

Design of Cruise Missile Controller Based on Robust TLC Method

Based on trajectory linearization control,the design of controller of cruise missile is studied.It is considered that the performance of current TLC controller is effected by system modeling error and outside disturbance,a robust trajectory linearization control method is proposed and corresponding controller is designed.Then,with the Lyapunov method,a rigorous poof is demonstrated in order to guarantee the ultimate boundedness of all the signals in the closed loop system of the provided method.Finally,the proposed method is applied to the flight control system design of cruise missile,and its effectiveness is verified by simulation results.
