Abstract
A novel immersion and invariance (I&I) adaptive control with σ-modification is proposed for flexible air-breathing hypersonic vehicles in the paper. Based on the framework of backstepping, the controller is a combination of I&I adaptive control and σ-modification. The control system can not only deal with the significant aerodynamic parameter uncertainties in AHVs model, but also guarantee the stability of the adaptive law in the presence of unavoidable nonparametric uncertainties. With the introduction of σ-modification, the adaptive law is designed away from the problem of parameter drift. Moreover, the structured design process and taking amplitude/rate constraints of states and actuators into account make the control system feasible to engineering practice. The stability of the closed-loop system is demonstrated by Lyapunov theory and the effectiveness of the method is illustrated by numerical simulations.
