Ignore the impact of the quantizer; the sequence [[z.sub.k]] directly comes into the digital filter; by smoothing, the digital filter outputs a more reliable correcting sequence {[y.sub.k]} to digital clock: [y.sub.k] = D(z)[z.sub.k].

Quantization also has become a research hotspot these years, paper [17] notes that quantization process plays an important role in the networked control systems, an adaptive quantizer can help to alleviate network congestion and maintain system stability, paper [18] proposes a quantized state feedback strategy for global and asymptotical stabilization of the networked control systems, papers [19, 20] address the problem of output feedback control for networked control systems with limited information, it should be noted that the impact of quantification cannot be ignored, and, in [18, 19, 21], the quantization deviation is disposed as an uncertainty.
