Zero-Order-Hold Based Event-Triggered Control for a Class of Approximately Feedback Linearized Systems

In this article, a new event-triggered controller is proposed that combines a zero-order-hold mechanism for the global asymptotic stabilization of a class of approximately feedback linearized systems. Together with a new event-triggering condition coupled with a zero-order-hold mechanism, a novel approach to the system analysis is developed that differs from the traditional event-triggered control approach. Based on the new system analysis, a control parameter selection guide is then provided for the state convergence speed and the number of control input updates. Several comparative examples illustrate the improved features of the proposed control method over the traditional event-triggered control method.
