摘要
基于Lyapunov-krasovskii函数,研究时滞系统的无偏H∞和标准H∞滤波方法,给出两种滤波方法的不同。论证无偏滤波思想的优越性,即无偏滤波方法可对临界稳定或不稳定时滞系统的不可测量状态进行估计,并且滤波器设计的计算量也下降。通过仿真实例,验证无偏H∞滤波方法的可行性。
Based on Lyapunov-krasovskii function,this paper studies the unbiased H∞ and standard H∞ filtering methods and illustrates the differences between them.The advantages of unbiased filtering are proved: the unbiased filtering can evaluate the unmeasured state of stable or unstable time delay system and reduce computation load designed by filtering container.Through simulation examples,the feasibility of the unbiased filtering is proved.
