Abstract: In this paper, a hybrid predictive controller is proposed for a class of uncertain non-linear switched system with input constraints and unavailable state measurements. The main idea is to design a bounded non-linear controller and a predictive controller for each subsystem using Lyapunov functions and state observers, also a suitable switched law to stabilise the closedloop subsystem, and to provide an explicitly characterised set of initial condition. For the whole switched system, based on the state estimates, a suitable switched law is designed to ensure the whole closed-loop's stability. The simulation results for a chemical process show the validity of the controller proposed in this paper.
