- This paper presents an investigation of the event-triggered control problem for an active suspension system featuring a networked communication architecture and Dynamic Output Feedback Controller (DOFCs) while taking into account the possibility of failure in actuators. The event-triggering condition determines when it is necessary to transmit the observed variables of the plant to the controller, in order not to saturate the network. A Dynamic Output Feedback Controller is synthesized under LMI restrictions to guarantee the system stability with the Hinfinity criteria, using the Lyapunov-Krasovskii functional approach. As the failures in actuators affect the state space model of the system, a novel polytopic model is employed to approach the plant function. In order to prove a practical feasibility, control performance characteristics for vibration suppression are evaluated under various road conditions.
