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...
In this paper, we proposed a model based sensor fault tolerant control system embedded in a generic PIC microcontroller for use in a temperature control system. The model based fault tolerant control algorithm is embedded in the microcontroller for stand-alone real-time implementation. The algorithm consists of a PID controller element (for nominal control) and a fault compensating element. Results...
Faults in process control systems can cause undesired reactions and shut-down of a plant, and could be damaging to components, to personnel or the environment. The improvement of reliability, safety and efficiency of the system has become increasingly important. The fundamental purpose of a FTCS scheme is to ensure that faults do not result in system breakdown and although at a lower degree of system...
This paper presents an application of a sensor fault tolerant control (FTC) scheme on a flexible joint and flexible link. A linear observer is used to reconstruct the faults. Then the reconstruction is subtracted from the faulty sensors to form a 'virtual sensor' and this signal (instead of the normally used faulty output) is then used to generate the control input. This minimizes performance degradation...
This paper proposes a sensor fault tolerant control scheme for a large civil aircraft. It is based on the application of a robust method for sensor fault reconstruction using sliding mode theory. The novelty lies in the application of the sensor fault reconstruction scheme to correct the corrupted measured signals before they are used by the controller and therefore the controller does not need to...
