Abstract :
There are two key points in this work as the main objectives. The first is how to convert nth
order fuzzy differential equation into a first-order system of fuzzy differential equations using the
notion of upper and lower bounds of the fuzzy solution to constitute the so-called interval fuzzy
solution. The second is to solve the obtained system from the first step using a powerful method
(the backstepping method) to provide an asymptotically stable solution by applying direct methods
of stability (Lyapunov direct method).
