%X In this work, the main problem considered is the 
detection and the isolation of the actuator fault. A new formulation of 
the linear system is generated to obtain the conditions of the actuator 
fault diagnosis. The proposed method is based on the representation 
of the actuator as a subsystem connected with the process system in 
cascade manner. The designed formulation is generated to obtain the 
conditions of the actuator fault detection and isolation. Detectability 
conditions are expressed in terms of the invertibility notions. An 
example and a comparative analysis with the classic formulation 
illustrate the performances of such approach for simple actuator fault 
diagnosis by using the linear model of nuclear reactor.
