This paper proposes an improvement on observer design of discrete-time fuzzy systems based on an alterable weights method. Different from the recent result, a more effective ranking-based switching mechanism is developed by introducing a bank of alterable weights for the sake of making use of the size difference information of the normalized fuzzy weighting functions more freely than before. Therefore, a positive result can be provided in this paper, that is, less conservative conditions of designing feasible fuzzy observers can be obtained than those existing results, while the computational cost of designing feasible fuzzy observers is even less than the up-to-date one. Finally, two numerical examples are given to show the progressiveness of the proposed method.

基于变权法的离散时间模糊系统观测器设计



本文提出了一种基于可变权重方法的离散时间模糊系统观测器设计的改进方法。与最近的结果不同,通过引入一组可变权重,开发了一种更有效的基于排名的切换机制,以便比以前更自由地利用归一化模糊加权函数的大小差异信息。因此,本文可以提供一个积极的结果,即可以获得比现有结果更不保守的设计可行模糊观测器的条件,而设计可行模糊观测器的计算成本甚至比现有的还要少。一。最后,给出两个数值例子来说明该方法的先进性。
