Based on Event-Triggered Anti-disturbance Tracking Control for Hypersonic Flight Vehicles with T-S Disturbance Modeling

Abstract

In this paper, a novel based on event-triggered anti-disturbance dynamical tracking control is discussed for HFVs with unknown exogenous disturbances.Firstly,the event-triggered mechanism is introduced into the control system.Secondly,the external disturbance is described by T-S model and estimated by disturbance observer.Next,by combining state feedback with disturbance estimation,a PI-type feedback controller is proposed to ensure the HFV models stability and the output tracking error convergence zero.Finally,the simulation result shows the algorithm is effective.Meanwhile,it can obtain satisfactory tracking performance and anti-disturbance tracking performance.
