Abstract :
Multiple models are used to describe the behavior of the system running in different faulty mode. Multiple element controllers are set up according to the multiple models. Based on the multiple element controllers, a fault tolerant controller is formed by using Bayesian decision making method. When different fault happens, the fault tolerant controller proposed in this paper can make the output of the system trace the set point very well. The effectiveness of given method is tested by simulation
