The present study concerns the dissipativity-based synchronization problem for discrete-time switched neural networks with time-varying delay. Different from some existing research depending on arbitrary and time-dependent switching mechanisms, all subsystems of investigated delayed are permitted to be nondissipative. For reducing frequency, combined paradigm constituted by state-dependent strategies is then constructed. In light proposed dwell-time-dependent storage functional, sufficient...

H/sub /spl infin// stabilization problem for a class of linear systems with time-varying norm-bounded uncertainty is studied by means hybrid state feedback strategy. Suppose that there exist finite candidate static controllers in set controllers, and none the individual controller makes system stabilizable disturbance attenuation. When gain matrices are known, based on single Lyapunov function technique convex combination condition, switching law which uncertain switched attenuation...

This study addresses the issue of robust control for a class discrete‐time delayed non‐linear systems in presence controller failure by using probability‐dependent method.

Many DSP algorithms such as direct synthesis, phase sensitive demodulation, modulation filter were implemented in FPGA to realize auto balancing function circuit. Simulation results show that has good performance from low frequency up 10 MHz. For advantages cost-efficient high...

Incomplete information in a soft set restricts the usage of set. To make incomplete more useful, this paper, we propose an algorithm with missing data filling for set, which is filled terms association between parameters. Based on this, decision-making method to meet requirements different customers. At last, illustrative example provided show feasibility and validity our approach practical applications.

Summary This article addresses the passivity analysis and asynchronous feedback passification problems for a class of discrete‐time switched systems with dwell time constraint. By exploiting time‐dependent storage functions, state‐dependent switching strategy obeying constraint is constructed, solvability conditions are developed in form linear matrix inequalities (LMIs). Moreover, passive controllers formulated simultaneously. It has been shown that derived results also applicable to...

This research concerns the bumpless transfer control problem for a class of switched systems with time-varying delays.
