Network-based H∞ filtering using a logic jumping-like trigger

摘要: This paper is concerned with the network-based H"~ filtering for a stochastic system, where data transmission from system to filter completed via communication network. Network-induced delays, packet dropouts and disorders are unavoidable due use of First, logic zero-order-hold (ZOH) designed discard disordered packets actively. The network-induced delays modeled as an interval time-varying delay. By decomposing delay into N subintervals uniformly, be Markov jumping modes governed by chain. In order work out transition rate one mode another, jumping-like trigger embedded ZOH simulate switching process. Second, based on model together new integral inequality in setting, novel bounded real lemma presented ensure that resultant error mean exponentially stable prescribed performance. Then, sufficient condition existence desired filters provided terms set linear matrix inequalities. Finally, air vehicle employed show effectiveness proposed design method.
