Adaptive observer, fault detection, fault tolerance control.


The adaptive observer for the nonlinear time-varying continuous-time system has been proposed in this paper. Also, a novel state-space adaptive observer-based tracker scheme for nonlinear time-varying sampled-data systems, which have unanticipated decay factors in the actuators, has been proposed in this paper. Here, we utilize the advantage of digital redesign methodology to convert a theoretically well-designed analog controller/observer with a high-gain property into its corresponding low-gain digital controller/observer for a practical implementation.
