Abstract
The compensation for uncertain deadzone is of both theoretical and practical importance in the adaptive fixed-time control of switched systems. So far, there exists no result reported on this problem because it is difficult to construct a fixed-time controller in the presence of the complicated switched network topology and the deadzone input. By using a newly proposed mode-dependent power integrator (MPI) method and a fuzzy deadzone model, a novel mode-dependent fuzzy fixed-time controller is presented to overcome the above problem. The proposed MPI method is more applicable in practice than the power integrator method in which each subsystem in the underlying system has its own power integrator. Stability analysis and simulation examples can be utilized to confirm the feasibility of the presented design.
