摘要
为了设计出全阶的滤波器,同时使得滤波误差动态系统是正则的、无脉冲的,并且满足一定的H∞性能指标,研究了连续奇异系统的全阶H∞滤波器的设计问题.利用Lyapunov-Krasovskii泛函及二次型的积分不等式方法获得了滤波误差动态系统的H∞性能时滞相关的判据,给出了奇异系统的鲁棒H∞滤波器存在的时滞依赖的充分条件.最后的数值例子说明了该方法的有效性.
The design problem of full order H∞ filter for continuous singular system is addressed in this paper,in order to design satisfactory full order H∞ filter with regular and impulse-free filter error dynamics. Lyapunov-Krasovskii functional and quadratic inequality method was used to get H∞ time-delay criterion of filter error dynamics. A sufficient condition of robust H∞ filter existence of singular system is provided. Finally,a numerical example is given to verify the effectiveness and practicability of the design method.
