Abstract

This paper deals with the Mixed Logical Dynamical (MLD) approach. It allows to model the hybrid systems involved continuous, discrete dynamics and constraints. The resultant system is well-posed for Model Predictive Control (MPC) that is used as control strategy for the system. An active Fault Tolerant control is proposed. This approach is illustrated by a tank system. Simulations are performed using the Hysdel compiler to show the efficiently of this formalism and the fault tolerant MPC control.
