摘要:

针对拦截弹末段的制导控制问题,改善已有建模结果,采用智能控制方法设计一体化控制律。考虑近似线性化和忽略耦合因素引起的建模误差,采用模型误差补偿改进拦截弹动力学模型;结合弹目相对运动非线性模型,建立面向拦截弹末段的制导控制一体化(IGC)模型。对此非匹配型非线性系统,利用自适应动态面控制方法进行控制器设计,不仅消除系统非匹配不确定性对系统性能的影响,同时避免了传统反演法的微分膨胀问题,得到控制目标与执行机构指令之间的直接关系。通过与忽略建模误差的IGC 拦截仿真比较,实验结果表明本文IGC 控制效果的优越性。

Abstract:

An integrated control law is designed by modifying the existing modeling results and using the intelligent control method for the guidance and control of interceptor during the terminal course. While the modeling error caused by approximate linearization and ignoring couplings is taken into consideration, a model error compensation is used to modify the interceptor dynamics. A nonlinear model for the integrated guidance and control (IGC) is obtained. The adaptive dynamic surface control is proposed for the controller design of this mismatched nonlinear system. The influence of mismatched uncertainties on the system performance is eliminated, and the term explosion in traditional backstepping method is voided. The integrated control law is used to establish a direct relationship between control objective and actuators command. Compared with the controller which ignores the modeling error in interception simulation, the proposed controller shows better interception performance.

Key words: control and navigation technology of aerocraft, interceptor, integrated guidance and control, modeling error, adaptive dynamic surface control
