Adaptive fault-tolerant output regulation of linear systems with unknown dynamics and actuator faults

Abstract

In this paper, the adaptive fault-tolerant output regulation for the system with unknown dynamics is considered. Firstly, a data-driven algorithm is proposed to identify the system dynamics by solving the Riccati equation. Due to unneeded to solve the optimal controller, the iterative process of the algorithm is reduced. Based on the identified model, an adaptive controller is designed to compensate for the actuator faults which include both outage and loss-of-effectiveness faults. Moreover, the internal model of the exosystem is embedded in the adaptive fault-tolerant controller which can stabilize the system whether the actuator faults hold or not. Finally, the numerical simulation result shows the effectiveness of the proposed controller.
