- Abstract
In this paper, the problem of control for a class of continuous time linear systems based on Luenberger-like state observer is investigated. A cyber-physical system is considered, which is composed of the controlled object, communication channel, filter and remote controller. A state observer is designed by using the filtered received signal, based on which two controllers are designed to stabilize the system. The stability conditions of the state observers and closed-loop system are derived by solving a linear matrix inequality. It is proved that the control methods can guarantee that all the signals of the closed-loop system are uniformly ultimately bounded. The effectiveness of the proposed methods is confirmed by simulation examples.
