Fault Estimation and Fault Tolerant Control for Discrete-Time Dynamic Systems [PDF]
IEEE Transactions on Industrial Electronics, 2015 In this paper, a novel discrete-time estimator is proposed, which is employed for simultaneous estimation of system states, and actuator/sensor faults in a discrete-time dynamic system. The existence of the discrete-time simultaneous estimator is proven mathematically.
