导弹自适应反演控制器设计

Design of Adaptive Backstepping Controller of Missile

提出了一种应用反演控制技术的非线性自适应导弹控制系统的设计方法。首先采用自适应辨识算法来估计系统中存在的不确定性 ,然后利用反演控制技术处理系统中的非匹配不确定性 ,在虚拟控制中引入了微分阻尼项 ,有效地改善了系统动态性能 ,并应用Lyapunov稳定性理论证明了系统是全局指数稳定的。

A design method for nonlinear adaptive missile control systems is proposed based on backstepping control techniques Firstly an adaptive identification algorithm is used to estimate the uncertainty of the system, then backstepping control techniques is used to deal with the mismatched uncertainty of the system, the differential damp terms are introduced into the fictitious control terms that improve the transient performance of the system effectively It is proved by Lyapunov stability theorem that the system is globally exponentially stable Finally numerical simulation results are presented to demonstrate the effectiveness of the proposed method
