时滞系统的基于状态重置的控制器设计

A Reset Quantized State Controller for Linear Time-delay Systems

该文主要研究线性时滞连续系统下基于状态重置的动态量化反馈控制问题。为了解决网络控制系统中的带宽限制问题,使用了对数量化器;然后用状态重置观测器代替标准观测器来抑制量化跳变误差;构造了一种时滞系统lyapunov函数,判定系统渐近稳定。最后利用matlab和lmi工具箱成功获得控制器的增益,并且用数值例子去证明状态重置该算法的有效性。

This paper presents the problem that a reset quantized state control for linear time-delay system.We use the logarithmic quantizer to deal with limited bandwidth and introduce a reset state observer which based on the standard one to suppress sensor quantization effects.According to the Lyapunov method,it is still asymptotically stable that the system which is introduced reset technique.The controller gain of the system is obtained by using Matlab and linear matrix inequalities toolbox.Finally,we give a numerical example to illustrate the effectiveness of the proposed approach.
