Continuous characteristic model based adaptive control method for a class of uncertain nonlinear systems

This paper presents a novel control method which can guarantee ultimate boundedness for a class of uncertain nonlinear systems. A special model transformation approach is proposed to transform the uncertain nonlinear system to a linear time-varying system called continuous characteristic model. Then, based on the continuous characteristic model, we develop an adaptive control method to guarantee the stability of the closed loop system. Finally, the proposed method is illustrated by simulations.
