摘要
针对一类模糊预估控制系统,利用幅相特性分析法及描述函数分析法分别对系统的主、付回路的鲁棒稳定性进行了分析,并导出了鲁棒上界.
With respect to a class of fuzzy pre-estimate control systems,robust stability of the primary loop and the secondary loop is analyzed with description function and magni -tude-phase property respectively in this paper.The robust upper boundary is also deduced.
