Abstract: Abstract:A method for integrated design of fault diagnosis and fault tolerant is proposed for a class of sensor fault. First, the sensor effectiveness factor and the controller gain are taken as a whole, so we can construct a combined output feedback controller via the theory of regional pole assignment. Then an optimal estimation method is given to estimate the sensor effectiveness factor in real time, which can be used to solve the controller gain. The well designed combined controller can ensure the system achieving a good performance while the realtime estimated sensor effectiveness factor can ensure the control is realtime and rapid. Finally, numerical simulations demonstrate the effectiveness of the proposed approach.    

Key words: Keywords:fault diagnosis, fault tolerant, spacecraft, effectiveness factor, regional pole assignment
