This paper is concerned with the dynamic event-triggered H∞ control issue of singularly perturbed switched systems, in which a persistent dwell-time switching regularity is embraced. The dynamic event-triggered mechanism is introduced to reduce some unnecessary data transmitted in the communication network so as to that the system can maintain the desired performance under better resource efficiency. Under this communication mechanism, a singular perturbation parameter independent criterion is derived to guarantee the globally uniform exponential stability with an H∞ performance for the considered persistent dwell-time switched singularly perturbed systems. Based on the criterion, a method is presented for calculating the gains of the desired controller. Finally, a numerical example is provided to verify the rationality and validity of the proposed method.
