Direct adaptive actuator failure compensation control: a tutorial
TLDR
In this paper, the authors present a tutorial on direct adaptive failure compensation-based solutions for different types of control systems: state tracking using state feedback, output tracking using either state feedback or output feedback, for linear, parametric, and actuation uncertainties.Abstract:
A resilient control system is expected to have the capacity to restore the desired system stability and tracking performance in the presence of uncertain system faults such as actuator failures. While redundant actuators are used for actuator failure accommodation, uncertain actuator failures, whose failure time, pattern, and values may be unknown, can bring new challenges to feedback control design as such uncertain failures can introduce large structural, parametric, and actuation uncertainties. Two technical issues are associated with using redundant actuators: how redundant actuators should be coordinated for effective failure compensation control, and how a feedback control law should be adaptively designed to compensate uncertain actuator failures. In this paper, we present a tutorial on direct adaptive failure compensation-based solutions to these issues for different types of control systems: state tracking using state feedback, output tracking using state feedback or output feedback, for linear, ...read more

Adaptive asymptotic tracking control of uncertain nonlinear system with input quantization
TL;DR: A new tuning function control scheme which is designed on the basis of a novel decomposition of hysteresis quantizer ensures the global boundedness of all closed-loop signals and the asymptotic convergence of tracking error to zero and shows that the transient performance can also be improved with the proposed scheme.
