Application of model based sensor fault tolerant control system

Fault tolerant control system (FTCS) provides an efficient technique to ensure the system goal to be achieved in spite of faults. This paper proposes the application of model based sensor fault tolerant control system for truck pulling a trailer system, an automobile suspension system and filed-controlled direct current (DC) motor system. The fault tolerant control design is divided into two parts which are a nominal performance controller and a model based element to provide sensor fault compensating signals. In this paper, the PID controller is used as a nominal controller that specifies the performance specification. When a sensor fault is present, the controller input is augmented to compensate the fault. Simulation results of real time implementation for truck pulling a trailer system, an automobile suspension system and field controlled DC motor system shows the effectiveness of the proposed design.
