| 中文摘要 |
| 数据量化是网络控制系统解决带宽有限的主要方法. 但是量化数据时可能产生的量化跳变又对系统的可靠性产生影响. 本文针对抑制量化跳变对系统的影响, 研究了一种状态重置动态量化反馈控制器. 首先设计状态重置观测器使发生量化跳变的系统可靠性不变. 然后基于状态重置后的特性, 结合概率论和随机过程, 得到一种动态量化反馈控制器.验证了状态重置动态量化反馈控制系统是渐近稳定的.通过MATLAB/LMI工具箱, 可得到控制器增益. 最后根据数值仿真例子, 验证了所提出的状态重置动态量化反馈控制的算法是行之有效的. |

| Data quantization plays an important role in networked control system with limited bandwidth communication channels. However, the quantitative data-jumping produced in data quantization may deteriorate the reliability of the system. To deal with this problem, we design a controller to suppress the data-jumping. Firstly, a reset state-observer based on the standard quantizer is introduced to ensure the reliability of the closed-loop control system when the data-jumping is occurred. According to the probabilistic and stochastic properties of the reset quantized states, we develop a reset quantizedstate controller to guarantee the asymptotic stability of this closed-system. The controller gain can be obtained by solving a class of convex linear matrix inequalities with MATLAB/LMI Toolbox. A numerical simulation example illustrates the effectiveness of the proposed approach. |
