Some new results on stability and input to state stability of fuzzy differential equations

In this paper, we introduce a new notion of stability, namely generalized practical h−stability. Both generalized practical h−stability and generalized input-to-state practical h−stability are considered. Under Lyapunov techniques, some sufficient conditions are given which guarantee generalized practical h−stability of fuzzy differential equations. The generalized practical h−stability analysis is also accomplished with the help of the scalar h−stable functions.
