In this paper, the problem of deep-stall recovery will be studied for the aircraft without longitudinal static stability. A new longitudinal short-period deep-stall model is established in the presence of time-varying distributed delays. Based on bifurcation analysis method, the effects of actuator fault on deep stall are analyzed in depth. Considering the system uncertainty, actuator fault, input saturation and unsteady disturbance, a finite-time prescribed performance deep-stall recovery law is designed according to the bifurcation analysis results. Further, to avoid the singularity problem in traditional finite-time control, an improved finite-time control law is developed. Stability of the closed-loop system is proved by common Lyapunov functional method. And simulations are given to illustrate the validity of the proposed deep-stall recovery control scheme.
