Robust stabilization of time-varying delay systems with pbkp_redictor-observer based controller

Abstract:

This papers deals with the problem of robust stabilization of a class of discrete systems with time-varying input delay and model uncertainties, where the state is assumed not to be fully accessible. Thus, a pbkp_redictor-observer based controller is proposed. Furthermore, a control synthesis algorithm based on the Cone Complementarity Linearization (CCL) approach is provided to design the controller and observer gains, with the objective of improving robust performance against uncertainties in the process model and the input delay. Finally, different illustrative simulations are introduced to show the main benefits of this strategy.
