Self triggered sliding mode control for Digital Fly by Wire aircraft system
Abstract The present work copes with the sliding mode control problem for the lateral directional dynamics of Digital Fly by Wire aircraft, which is modeled as Markovian jump systems due to sudden change of the internal parameter. The triggered condition is developed, combining with the designed triggered sliding mode controller, to ensure the reachability of the sliding domain around the specified sliding surface. And then, the sufficient condition is derived to achieve the uniform boundedness of the system state when remaining in the sliding domain. Furthermore, based on the proposed triggered condition, a mode independent self triggered scheme is designed to determine the triggering instants, according to which the next triggering instant can be computed in advance by utilizing the state information at current triggering instant. Finally, the simulation results are given to validate the proposed method.
