Type-2 Fuzzy Adaptive Control Method of Ecological System
Maomao Xia, Yimin Li, Yang Cai · 2012
In this paper, a type-2 fuzzy adaptive controller of a Lotak-Volterra system is considered. For bettering the active system properly, the approximated error is introduced into the design of the controller. By using Lyapunov synthesis approach, we attain an adaptive law adjusting the free parameters in the controller such that the closed-loop system follows a desired trajectory. The nonlinear dynamic behavior and control of biomathematic system state are theoretically discussed, which are of practical significance. The scheme in- dicates that a type-2 fuzzy adaptive controller is a powerful tool to pursuit sustainable development of ecology.
