Abstract:

This paper aims at proposing a dynamic aperiodic discrete mechanism based on event-based triggering and quantization for nonlinear systems considering time delay and disturbances. First, a dynamic event-based device for nonlinear systems subject to time delay is proposed with a state observer. The stability of the system is confirmed with an output-feedback control scheme and the Lyapunov-Krasovskii functional (LKF) technique. Then, a state observer and a disturbance observer are constructed with a new coordinate transformation for the nonlinear systems with external disturbances. A combined dynamic event-based sampling and quantization method is designed for the estimated states and disturbances. With the sampled and quantized estimated variables, an output-feedback control algorithm is presented to assure the boundedness of the closed-loop nonlinear systems with the LKF technique. Moreover, the Zeno behavior is avoided with the designed dynamic aperiodic discrete mechanisms. Finally, two examples are provided to present the feasibility of the designed event-based and quantized control method.
