在网络控制系统中，如果通信信道的速率不够高，则应将传输的数据量化为相对较少的位数。我们提出了一种反馈量化器，用于可实现的简单量化器，具有高精度的网络控制。无限脉冲响应（IIR）反馈滤波器旨在减轻反馈控制系统性能约束下量化误差的影响。然后，通过数值计算获得达到约束的最小速率。提供仿真来显示所提出的量化器在网络反馈控制系统中的有效性。
In networked control systems, transmitted data should be quantized into a relatively small number of bits if the rate of the communication channel is not sufficiently high. We propose a feedback quantizer for an implementable simple quantizer with high precision for networked control. The infinite impulse response (IIR) feedback filter is designed to mitigate the effect of the quantization error under a performance constraint of the feedback control system. Then, the minimum rate that achieves the constraint is numerically obtained. Simulations are provided to show the effectiveness of the proposed quantizer in a networked feedback control system.
