反舰导弹自适应模糊滑模控制系统设计

Control System Design of Anti-Ship Missiles Based on Adaptive Fuzzy Sliding-Mode Control

摘要:

针对反舰导弹的纵向过载控制系统设计问题,提出了一种自适应模糊滑模控制设计方法。将反演设计、模糊逻辑系统、自适应控制和滑模控制等方法结合,利用模糊逻辑系统估计被控系统的虚拟控制量；应用自适应设计方法逼近系统不确定项的未知上界；运用反演设计方法得到系统的虚拟控制量和实际控制量。基于Lyapunov稳定性理论,证明此闭环系统的所有误差信号均有界且指数收敛至原点的有界邻域内,仿真结果验证了该方法的有效性。

Abstract:

An adaptive fuzzy sliding-mode control method was presented for the control system design of anti-ship missiles. Firstly, fuzzy logic systems were used to estimate the virtual control laws of the controlled system. Secondly, the adaptive control method was employed to estimate the unknown upper boundaries of uncertainties. Lastly, the backstepping design was incorporated to design the virtual control laws and actual control law of the controlled system. Based on Lyapunov stability theorem, all of error signals were bounded and exponentially converge to a bound neighbor of the origin. Simulation results validated the effectiveness of the proposed control method.
