This paper presents a novel adaptive tracking control method for a class of systems which can be described with a first-order characteristic model by the theory of characteristic modeling. An approach is introduced to compress the system characteristics into a special time-varying parameter, which can simplify the model and be easy for application in practical engineering. Lyapunov-based techniques are used to guarantee the stability of the closed loop system. The effectiveness of the proposed method is illustrated by simulations.
