“…For the source of double fuzzy summation, Pólya's theory [37,27] is exploited to offer progressively necessary and sufficient conditions which generalizes some earlier 25 works [26,10]. For the source of quadratic Lyapunov function, more general types of Lyapunov function candidates such as fuzzy Lyapunov function [29,5,24,18], piecewise linear Lyapunov function [11,12], switching Lyapunov function [32,21] and polynomial Lyapunov function [4,21] function-independent stability conditions, the membership-function-dependent approach is applied to make the stability conditions depend on membership functions such as using approximated membership functions [30,17], polynomial constraints [38], symbolic variables [39,22,23] and other techniques [3,20,16,18,7]. 35 Another task of the development of FMB control strategy is to extend it to solve control problems [40,33,42,55,43,8,15,25,54].…”
