摘要
利用模糊结构元方法,定义了模糊数和模糊值函数的线性运算和乘法运算,研究了由模糊结构元线性生成的模糊微分系统的稳定性问题,得到了Lyapunov意义下稳定、渐进稳定和指数稳定的结果.同时,给出了具体的实例.
In this paper, we defines the linear operation and multiplication for fuzzy num- ber and fuzzy-valued function, and investigates the stability of fuzzy differential systems which are linear formed by fuzzy structured element, we obtain the result of Lyapunov sta- bility, asymptotically stability, exponential stability. At last, the author put forward two examples.
