制导炮弹离散自适应滑模控制器设计
Design of Discrete-time Adaptive Sliding Mode Controller for Guided Proj ectiles
摘要
Abstract
The discrete-time adaptive sliding-mode-controller for guided proj ectiles with parameter error was proposed.Considering the nonlinear coupling characteristics of the system,input-output feedback linearization was utilized to transform the system model into two standard form subsystems.The subsystems were discretized,and a discrete-time controller for guided proj ectiles was designed based on sliding mode control principle.In order to diminish the switch width of the discrete-time sliding mode system corresponding to parameter error,a dead-zone parameter adaptive-law was designed.The stability of the uncertain closed-loop system was proved by Lyapunov theory,which made the controller have high robustness.Simulation result indicates that the proposed controller is robust with respect to large aerodynamic parametric uncertainty,and has excellent dynamic tracking performance.关键词
