Abstract
This paper proposes a new velocity measurement algorithm by measuring the velocity emf of electric actuator with high accuracy. First of all, the principle of measurement using in this algorithm is presented. Then, the whole structure and function of each element in this algorithm are explained. Also, the analysis of the adaptive control system, which is included as a component of this algorithm, is given. After all, results of the simulation experiments verify that the proposed method is valid to design velocity measurement algorithm.
