Description

<jats:p> In order to achieve stable and rapid track seeking, a repetitive track seeking algorithm, which realizes highly accurate velocity control through velocity error integration, has been developed. Simulations and experiments show that the algorithm is effective in optical head velocity control. The algorithm reduces velocity error, compared with the conventional approach, so that the transient response at the seek end is greatly improved. The total seek time is reduced by adopting a reference velocity trajectory with larger deceleration rate, using this algorithm. </jats:p>
