We study adaptive fault-tolerant tracking control for uncertain linear systems. Based on recent results in funnel control, and the time-varying Byrnes-Isidori form, we develop a low-complexity model-free controller that achieves prescribed performance of error any given sufficiently smooth reference signal. Within considered system class, allow more inputs than outputs as long certain redundanc...

In this paper a theoretical framework of robust fault-tolerant control (FTC) for a class of nonlinear nonaffine-in-control systems is developed. In the framework, an observer-like auxiliary system is designed via adaptive and sliding mode techniques, which is only required to ensure that the output of the auxiliary system asymptotic tracking plant output. Based on the auxiliary system, a reconf...

Flux coupling in heteropolar magnetic bearings permits remaining active coils to assume actions of failed coils to produce force resultants identical to the un-failed actuator. This fault-tolerant control usually reduces load capacity because the redistribution of the magnetic flux which compensates for the failed coils leads to premature saturation in the stator or journal. A distribution matr...
