A control law synthesis conditioned by the reliability of actuators in the presence of failures is presented in this paper. The aim is to preserve the health of the actuators and the availability of overactuatued system both in the nominal situation and in the presence of some actuator failures. The reliability assessment is computed by Bayesian Network since it is well suited to model the reliability of complex systems with simple parameter matrices and also to compute actuators reliability given evidences through the bayesian inference. It is applied on a system to estimate its reliability and those of its components and provide the parameters to synthesize the control laws. The effectiveness and the performances of the developed method are illustrated on a subsystem of a drinking water network.
