Quantized H∞ filtering for singular systems

This paper addresses the problem of quantized H_∞ filtering for linear singular systems. The communication channel we consider encounters in the ideal case. For the ideal channel, we design a filter to mitigate the quantization effects, which ensures not only the robust stability but also a prescribed H_∞ filtering performance for the filtering error systems. A sufficient condition is derived for the filtering error system to be admissible and achieve a prescribed H_∞ noise attenuation performance. Finally, an illustrative example is given to show the effectiveness of the proposed results.
