Abstract:In the non-uniformly sampled systems, there are uncertainties and time-varying of the refresh time interval, which have caused great difficulties to design the system controller. To aim at these problems, the refresh time interval is regarded as the time delay variable, and the system dynamic changing processes in different time delays are characterized by the changing processes of different subsystems. The variety of different time delays is transformed into the switching between different sub-models. The non-uniformly sampled system is described as a class of discrete-time switched systems with finite subsystems. Under the condition of satisfying the average dwell time, the output feedback control method is used to guarantee the exponential stability of the closed loop non-uniformly sampled system. Finally, the effectiveness of the proposed method is demonstrated by the example of the non-uniformly sampled system. © 2020, Chinese Institute of Electronics. All right reserved.
