Fault Diagnosis in Feedback Control Systems and Fault-Tolerant Architecture
In practice, model-based fault diagnosis is often integrated into a feedback control loop, in order to enhance the system reliability and availability. The study on fault diagnosis in feedback control systems is thus of special interest in many real applications. The major focus of this chapter is on the residual generation in a feedback control loop without an observer running parallel to the controller and, based on it, the realization of fault detection schemes.
The basis of the residual generation and fault detection schemes is an observer and residual generator based realization of the Youla parameterization of all stabilization controllers, which allows residual generation embedded in the control loop and building of a fault-tolerant architecture. The last part of this chapter is dedicated to the realization and implementation of residual generation and fault detection schemes in different control configurations.
