预设时间性能约束下高超声速飞行器的自适应容错控制
Adaptive fault-tolerant control of hypersonic vehicle under preset time performance constraints
摘要
Abstract
An adaptive fault-tolerant backstepping control strategy is proposed for the tracking control problem of hypersonic vehicle under output error constraints,uncertainties and actuator faults.Firstly,an exponential preset time performance function is designed to ensure that the output error meets the constraint requirements within the preset time.Secondly,the uncertain term and elevator fault are solved by adaptive law.The tracking differentiator is used to solve the"explosion of complexity"problem and avoid the higher-order derivation of the virtual control input in backstepping control.Finally,the stability of the closed-loop system is proved based on Lyapunov theory,and the effectiveness of the control strategy is verified by simulation.关键词
