Abstract: This paper gives a controller for a fault tolerant model predictive control when a fault occurs at output feedback loop. Fault tolerant control is to control safely even when a fault occurs. That is, the steady gain does not change at a fault and transient response has not a large overshoot. The transient response is decided by the poles of the closed-loop and the controller. Hence, this paper derives the mathematical expressions of specifications: 1) the closed-loop poles; 2) the controller poles; 3) the steady gain at the output feedback failure by using symbolic processing software. Using the obtained expressions this paper gives a straightforward design procedure.
Keywords: fault tolerant control; model predictive control; extended controller; steady gain; closed-loop poles; controller poles; symbolic processing software; Gröbner basis.
