Abstract
AbstractIn this article, the security control problem of a class of high‐order nonlinear cyber‐physical systems is investigated where the actuator and sensor are suffered from deceptive cyber‐attacks. By assuming that only the contaminated system output is available for feedback control, a set of K‐filters are applied to develop a novel observer to reveal the state information, and based on which an adaptive control law is designed. It is shown that asymptotic stability of nonlinear systems and boundedness of all the closed‐loop signals can be guaranteed using backstepping method even in presence of adversarial attacks. Simulations results illustrate the effectiveness of the proposed algorithms.
