Aiming to solve the problems of incremental photoelectric encoder eccentricity in the speed control system of rolling mill, this paper deduces the calculation model of actual speed, and gives a high precision approximation calculation method. Furthermore, the effectiveness and accuracy of the simplified model are verified by the simulation results. The online identification method of eccentricity and initial angle is also given in the paper. In addition, on the basis of continuous model, this article derives from the discrete model of traditional speed measurement scheme based on digital control system. This proposed algorithm has simplicity and excellent application value, and the effectiveness of the algorithm has been verified.
