Abstract
In this article, a fragility-free prescribed performance control (PPC) approach is proposed for unknown disturbed non-affine systems with application to flight control of waverider aerocraft (WA). The main improvement is to develop a prescribed funnel containing additional re-adjusting terms, which is able to autonomously re-adjust its shape, such that the tracking error, whose value may increase due to parametric perturbations and external disturbances, is always constrained within the prescribed funnel, capable of guaranteeing, for any initial system condition, (1) avoidance of security fragility problem associated with the existing PPC, (2) finite-time prescribed performance concerning tracking errors, and (3) independent of affine model formulation and function approximation. Finally, the addressed design is applied to WA, and compared simulations with practical examples are presented to show the superiority.
