Abstract

In this paper, we investigate the finite-time output feedback control for discrete asynchronous switched systems with input saturation and output saturation based on MDADT. Firstly, we solve the input saturation and output saturation problem by employing a low-gain output feedback controller and the sector nonlinear condition. Secondly, we consider the asynchronism under event-triggered strategy and use the MDADT approach for finite-time stabilization and boundedness of the discrete-time switched systems under asynchronous switching. Some sufficient conditions in terms of LMIs and the appropriate MDADT are provided. Finally, two examples are given to show the effectiveness of the theoretical results.
