Abstract:

This paper investigates the overload stabilization problem of the rolling-missile subject to parameters uncertainty and actuator saturation. In order to solve this problem, a sliding-mode control (SMC) scheme is technically employed by using the backstepping approach to make the dynamic system stable. In addition, SMC with the tanh-type switching function plays an important role in reducing intrinsic vibration. Furthermore, an auxiliary system (AS) is developed to compensate for nonlinear terms arising from input saturation. Finally, the simulation results provide a solution to demonstrate that the suggested SMC and the AS methodology have advantages of strong tracking capability, anti-interference ability and anti-saturation performance.

Key words: input constraint, back-stepping approach, slidingmode control (SMC), auxiliary control system
