该技术说明使用有限级量化器研究了离散时间线性系统的输出反馈控制。主要目的是找到一种易于实施并实现渐近稳定的量化策略。基于已知的对数量化方案，我们为量化器引入了一种简单的动态缩放方法。给出了优化量化水平数量和相应量化动态输出反馈控制器的设计的次优方法。还检查了动态量化方案相对于输入干扰的鲁棒性。
This technical note studies quantized output feedback control of discrete-time linear systems using a finite-level quantizer. The main objective is to find a quantization strategy which is easily implementable and achieves asymptotic stabilization. Based on a known logarithmic quantization scheme, we introduce a simple dynamic scaling method for the quantizer. A suboptimal approach for the optimization of the number of quantization levels and the design of a corresponding quantized dynamic output feedback controller is given. The robustness of the dynamic quantization scheme with respect to input disturbances is also examined.
