Abstract
In this paper
an improved deadbeat control strategy is presented because the conventional deadbeat control property is subject to be affected by the parameter of power system. In order to improve the track accuracy of the system
the on-line identification parameter method is used and the parameters of controller can be corrected instantly. As a result
the controller is adaptable to the change of the system parameters. Hence the performance of track is improved effectively.
