高超声速飞行器指定时间时变高增益反馈跟踪控制
Prescribed-time Tracking Control of Hypersonic Vehicles by Time-varying High-gain Feedback
摘要
Abstract
The prescribed-time tracking control problem of hypersonic vehicles in the presence of unknown environ-mental disturbances in the control channel is studied.Based on the input-output linearization model of hypersonic vehicles and some properties of a parametric Lyapunov equation,a smooth and bounded time-varying high-gain controller is proposed.Compared with the existing finite/fixed time control methods for hypersonic vehicles,the chattering phenomenon does not appear in the algorithm,and the convergence time does not depend on the initial state and can be set in advance.When the hypersonic vehicle has unknown bounded environmental matched dis-turbance,the proposed controller can ensure that the altitude and velocity track the reference signals in the pre-scribed time.Finally,simulation results verify the effectiveness of the proposed method.关键词
