| Abstract: | This paper aims for precise tracking with disturbance rejection and low energy consumption. An event‐triggered controller based on a sampled‐data enhanced extended state observer (SD‐EESO) is designed for a networked tracking system. In this method, the measured output and the given signal are sampled and transmitted to an observer, which is designed to periodically estimate the negative disturbance and tracking errors. Furthermore, a dynamic event‐triggered state feedback–feedforward controller is developed. It is shown that as long as the sampling period satisfies the given condition, the estimation error and the tracking error are both globally bounded stable. The numerical simulation and the direct current (DC) brush motor position control example show the superiority of the designed control scheme. [ABSTRACT FROM AUTHOR] |
