  Since the presence of chaos in Bose-Einstein condensate (BEC) systems plays a
destructive role that can undermine the stability of the condensates,
controlling the chaos is of great importance for the creation of the BEC. In
this paper, a fuzzy logic controller (FLC) to synchronize the chaotic dynamics
of two identical master-slave BEC systems has been proposed. Unlike the
conventional approaches, where expert knowledge is directly used to construct
the fuzzy rules and membership functions, the fuzzy rules have been constructed
using Lyapunov stability theorem ensuring the synchronization process. The
effectiveness of the proposed controller has been demonstrated numerically.
