Abstract: A dual-mode predictive controller of discrete nonlinear system is proposed using the fuzzy system as a predictive model. In the neighborhood of the origin, a linear feedback controller designed for the linearizing system generates the control action. If outside this neighborhood, however, a predictive controller based on fuzzy model applies to the real nonlinear system and drives the trajectory of the nonlinear system to the attractive region. The closed-loop stability is guaranteed under some conditions. A simulation is done to exemplify the effectiveness of the scheme proposed.
