本文研究了SISO LTI对象模型的网络控制，其中通信信道同时受到量化和数据丢失的影响。使用一个标准的信号-噪声比约束的白色噪声模型的量化，我们推导出编码器-解码器对，最大限度地减少了闭环性能上的信道伪影的影响。此外，我们提供了一个简单的必要和充分条件，保证所考虑的网络控制系统架构的稳定性。
This paper studies networked control of SISO LTI plant models, where the communication channel is subject to both quantization and data dropouts. Using a standard signal-to-noise ratio constrained white noise model for quantization, we derive coder-decoder pairs that minimize the impact of channel artifacts on closed loop performance. In addition, we provide a simple necessary and sufficient condition that guarantees the stability of the considered networked control system architecture.
