A design method of initial value for adaptive feed-forward control using support vector machine

This paper presents design method of initial value in adaptive feed-forward control by using support vector machine. The adaptive feed-forward control are implemented to compensate for disturbances induced position error signals in positioning control systems. Although the effectiveness was verified in previous studies, experimental results show that the adaptive control have mainly two problems. The adaptive algorithm requires time to converge the adaptive parameters and the performance may vary in experiments. To overcome the problems, we have developed an improvement method of convergence for adaptive feed-forward control by setting initial values. The experimental results in hard disk drives show that the proposed method can improve the convergence time and the performance variation.
