A robust super twisting fractional-order sliding mode-based control of vehicle longitudinal dynamic subjected to a constant actuator fault

This paper deals with the design and analysis of a super twisting fractional-order sliding mode controller (ST-FOSMC) to adjust vehicle longitudinal dynamic when braking. While loading, road types, modeling uncertainties are time-varying parameters, control law must be robust against these disturbances. Also, aging brake plate may introduce difference between output actuator response that should considered. The proposed strategy has been used enable anti-lock braking system (ABS) track desired wheel slip value despite presence disturbances constant fault. this is presented stability guaranteed by applying Lyapunov theory. We carried out simulation example makes comparison our one based on investigate which them outperforms other. results exhibit superiority fractional order over traditional during phase.
