Integral-based event triggering actuator fault-tolerant control for an active suspension system under a networked communication scheme

This paper presents a research on the problem of enhancing ride safety and comfort during driving of a vehicle using an active suspension control system under a networked communication. An integral event-triggered condition is defined to reduce the network usage over time, a Dynamic Output Feedback Controller is designed under the <tex-math notation="LaTeX">H_∞</tex-math> criteria and Lyapunov-Krasovskii functionals to guarantee the system stability, actuator faults are considered for the controller design. The control algorithm is solved in terms of Linear Matrix Inequalities. In order to prove a practical feasibility, control performance characteristics for vibration suppression are evaluated under various road conditions.
