Multiple models adaptive control for a class of nonlinear system

Despite the multiple models adaptive control approach has been proposed ten years ago, the field is not sufficiently mature to meet the challenging control problems where strict performance and stability are required. The most likely difficulty is the stability of the system with multiple models adaptive controller cannot be established easily. Towards this goal, this paper develops a novel multiple models adaptive controller for a class of nonlinear system in parameter-strict-feedback form which not only improves the transient performance significantly, but also guarantees the stability of all the states of the closed-loop system. A simulation example is proposed to illustrate the effectiveness of the developed multiple models adaptive controller.
