FAULT TOLERANT CONTROL DESIGN WITH ACCEPTABLE PERFORMANCE DEGRADATION

The main objective of this work is to design a fault tolerant control approach using multiple model technique and with acceptable performance degradation due to faults in actuators, sensors and system dynamics. The achievable performance under various component failures is represented in the form of reference models, known as acceptable performance reference models. These models are used to synthesize a set of controllers. Under a specific fault condition, proper controller is reconfigured and revised command inputs are selected automatically to achieve desired performance. The aircraft model is chosen to demonstrate the effectiveness of the model.
