基于LMI的范数有界不确定仿射离散时滞系统的鲁棒控制

摘要

针对一类带有时滞的范数有界不确定仿射离散系统,为了研究其相应闭环系统鲁棒稳定性,采用构造相应二次Lyapunov函数的方法,结合线性矩阵不等式(LMI)技术,设计出系统稳定的状态反馈鲁棒控制器.获得了该仿射系统渐进稳定的一个充分条件,从而表明该仿射系统渐进稳定性是可实现的.线性矩阵不等式可以利用已有的凸优化技术求解.最后通过仿真算例验证了该方法的正确性和有效性.%In order to solve the hysteretic nature of artificial identification in the most of domestic coal mine and improve the rate of coal mining,the method of coal petrography identification is adopted based on the image recognition technology. According to the significantly different of coal petrography s grey value and texture to extract them respectively. On this account of judgment basis to go for identification of coal and rock.
