研究了参数不确定系统通过有损信道和数据速率受限信道的镇定问题。我们提出了一种量化方案，与使用均匀量化器的情况相比，它有助于降低稳定所需的数据率；现有的处理不确定系统在通信信道上的控制的工作通常使用均匀量化器。对于采用新量化器的系统，给出了一个充要条件和一个充分条件。这些条件展示了数据速率、分组丢失率和用于稳定的对象参数的不确定性界限之间的限制和权衡。
This paper considers stabilization of parametrically uncertain systems via lossy and data-rate-constrained channels. We propose a quantization scheme which helps to reduce the required data rate for the stabilization compared with the case using the uniform quantizer; the existing works tackling the control of uncertain systems over communication channels commonly use the uniform quantizer. For systems utilizing the new quantizer, a necessary condition and a sufficient condition are derived. The conditions demonstrate limitations and tradeoffs among data rate, packet loss probability, and uncertainty bounds on plant parameters for stabilization.
