Sliding-mode control for a rolling-missile with input constraints

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 back-stepping 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.
