This article investigates the observer-based security control of discrete-time Markov jump systems (MJSs) subject to hybrid cyber-attacks and unmeasured states via event-triggered scheme. The event-triggered scheme (ETS) is being developed to relieve more network burdens. A Luenburger observer is used to estimate the unmeasured states. In this work, the hybrid cyber attack is addressed, which contains deception attacks and DoS attacks. It is anticipated that input control signals sent across a network are vulnerable to hybrid cyber-attacks in which adversaries could inject fake data into the control signals. Since system state information is usually not fully known, an observer-based controller is built to stabilize the system and keep the right performance index even when hybrid cyber-attacks happen. By solving linear matrix inequalities (LMIs), the controllers and observers are also obtained. Lastly, inverted pendulum applications are shown to show how well and realistically the theoretical results can be used to respond to and get rid of the effects of hybrid cyber-attacks.
