H∞ Filtering for a Class of Networked Systems with Randomly Occurring Quantizations
In this paper,the H∞ filtering problem is investigated for a class of discrete-time networked systems with randomly occurring quantizations (ROQs). Logarithmic quantizers with different quantization laws are considered and a Bernoulli distributed stochastic sequence is utilized to determine which quantizer is used at a certain time instant. After converting the quantization effects into sector-bounded parameter uncertainties,a suf.cient condition ensuring the existence of the desirable.lters is proposed by using the Lyapunov function approach,and the parameters of the desired.lters can further be obtained. A numerical example is employed to illustrate the applicability of the proposed technique.
