STT飞行器反步自适应滑模控制方法
Method of Backstepping Adaptive Sliding Mode Control for STT Aircraft
摘要
Abstract
A backstepping adaptive sliding mode control method is proposed for STT aircraft atti-tude tracking control with large deviation,external disturbance and model uncertainty.The atti-tude dynamic model of STT aircraft is established and linearized,and a three-channel decoupling attitude mathematical model oriented to control is obtained.The controller is divided into an outer loop overload controller and an inner loop angular velocity controller,and double loop controllers are designed based on sliding mode control theory.At the same time,adaptive law is designed to compensate for the disturbance,so that the attitude control system has good adaptability and ro-bustness.The stability of the designed controller is proved by the Lyapunov stability theorem.The numerical simulation results show that the overload tracking error is less than 0.1,the angu-lar velocity tracking error is less than 0.5(°)/s,and there is no full deflection and chattering of the aerodynamic rudder.The effectiveness and feasibility of the designed controller are verified by the numerical simulation results.关键词
