Abstract:

In this paper, an adaptive prescribed-time/performance control method is proposed for the plane-symmetric aircraft in the boost phase subject to thrust misalignment, significant asymmetric aerodynamics, and high-altitude wind shear. This method allows the convergence time and steady-state accuracy of attitude control to be conveniently pre-set using two independent parameters of the process function. Firstly, a dynamic model of the plane-symmetrical aircraft is established and transformed into a double-integrator cascaded control-oriented model. Secondly, a piece-wise continuous process function is designed to constrain the convergence time and steady-state accuracy, and an unconstrained system is obtained by using barrier function-based transformation. Thirdly, based on the backstepping method, an adaptive control law is designed to ensure the boundedness of the unconstrained variables. A segmented continuous function is introduced to avoid control chattering, and a neural network is employed for adaptive approximation and disturbance compensation. To address the singularity issue of the prescribed-performance control method with large deviations caused by wind shear, a reset strategy of process function is devised to relax the constraint boundaries and eliminate control singularities. Finally, the stability of the closed-loop system is proven based on the Lyapunov method, and the effectiveness of the control method is validated through numerical simulations.
