Nonlinear internal model control based on transformed fuzzy hyperbolic model

A nonlinear internal model control based on transformed fuzzy hyperbolic model is proposed for unknown nonlinear discrete-time dynamical system in this paper. The internal model controller is derived from the transformed fuzzy hyperbolic model. The transform is based on property of hyperbolic tangent function and reduces the complexity of controller design. The robustness of system is guaranteed by the filter. The stability of inverse control system is demonstrated. The simulations demonstrate the performance of internal model control scheme based on transformed fuzzy hyperbolic model.
