In this paper, the problems of stability for continuous and discrete-time polytopic uncertain switched linear systems with average dwell time switching are investigated. Firstly, the exponential stability result of general continuous-time switched systems using a discontinuous piecewise Lyapunov function approach is revisited, and the discretetime counterpart is then presented by the following ...

In heterogeneous networks (HetNet), it is an important issue to determine a suitable access network for call request to support seamless service and stable connectivity. For moving user equipment (UE), when and how to select a appropriate cell is more challenging. Since relatively long handover (HO) interruption time occurs due to the frequent HO, they experience significantly degraded data rat...

This paper deals with the problem of exponential stability of linear switched delay systems. An average dwell time method is introduced into linear switched delay systems for the first time and LMIs’ conditions are presented to guarantee robust exponential stability of such systems. A lower bound of average dwell time is given. Exponential decay estimates for the states of such systems are also...

This article considers a hypothetical imaging device with a spinning slat collimator that measures parallel-planar-integral data from an object. This device rotates around the object 180 degrees and stops at N positions uniformly distributed over this 180 degrees. At each stop, the device spins on its own axis 180 degrees and acquires measurements at M positions uniformly distributed over this ...

In this paper, we investigate the disturbance attenuation properties of timecontrolled switched systems consisting of several linear time-invariant subsystems by using a dwell time approach incorporated with piecewise Lyapunov functions. First, we show that when all subsystems are Hurwitz stable and achieve a disturbance attenuation level smaller than γ0, then the switched system can achieve an...
