摘要:
为实现远程制导炮弹的非线性控制,提出了一种基于滑模控制原理的非线性离散控制器设计方法。建立了远程制导炮弹控制系统模型,针对该模型存在的非线性和耦合问题,利用反馈线性化方法将复杂的非线性系统解耦为两个独立的线性定常子系统,然后对子系统作离散化处理,并结合滑模控制原理设计了远程制导炮弹的非线性离散控制器。弹道仿真结果表明:该模型和控制器是有效的,实现了制导炮弹系统的解耦控制,并对模型参数不确定具有一定的鲁棒性,而控制采样时间将引起动态跟踪误差。
Abstract:
In order to implement the nonlinear control for extended range guided projectiles effectively,a nonlinear discrete-time control strategy via the sliding mode control principle is proposed.The control system of extended range guided projectiles is modeled.Aiming at the nonlinear coupling characteristics for the system,input-output feedback linearization is utilized to decouple the system into two independent linear time-invariant subsystems in both lengthwise and cross directions.The subsystems are transformed into discrete-time systems,and a nonlinear discrete-time controller for extended range guided projectiles is designed based on the sliding mode control principle.Trajectory simulation results demonstrate that the model and controller are feasible,the proposed controller is robust with respect to model parametric uncertainty,and that the dynamic tracking errors will be induced by the sampling time.
