LMIs-based stability analysis and fuzzy-logic controller design for networked systems with sector nonlinearities: Application in tunnel diode circuit

In this article, the problem of exponential mean-square stability analysis is discussed for uncertain networked control systems expressed by a stochastic T-S fuzzy model. general, characteristics random occurrence multipath packet dropouts often exist in signal transmission network. For dealing with difficult point, dynamic output feedback strategy combining Bernoulli theory employed. Then, delay-dependent conditions are derived and closed-loop system exponentially stable designing fuzzy-basis-dependent Lyapunov functional. Furthermore, terms linear matrix inequalities (LMIs) technology, sufficient gained to guarantee prescribed H-infinity performance. Different from previous literatures, congruence transformation method employed determine controller gain matrices reducing computation complexity solving LMIs. Finally, proposed applied tunnel diode circuit model verify applicability.
