Fuzzy control of multivariable nonlinear systems subject to parameter uncertainties: model reference approach

Presents the control of nonlinear systems subject to parameter uncertainties under a fuzzy control approach. The nonlinear plant tackled in this paper is an n-order nonlinear systems with n inputs. A design procedure of a fuzzy controller is provided such that the states of the closed-loop system will follow those of a user-defined stable reference model despite the presence of parameter uncertainties. A numerical example is given to show the design procedures and the merits of the proposed fuzzy controller.
