A Resilient Guaranteed Cost Control Design Via the Robust Two-Stage LQ Reliable Control

This paper considers the LQR reliable control design problem for uncertain discrete-time systems which are subject to parametric uncertainty in both state and input matrices. A robust (fixed) version of the recently developed ATSLQRC, named as the RTSLQRC, is proposed to solve a resilient guaranteed cost control design problem for uncertain discrete-time systems in which the actuators may have some faults. The connections of this new robust control with existing results are addressed. A numerical example is also given to illustrate the proposed method.
