Abstract in different language:	Current state of research in the area of linear synchronous motor control is presented. Two control methods, vector control and forced dynamics control, are described for speed control of the drive. Both methods offer a dynamic speed response profile, which can be selected for given application by the user. In addition to this, the angle between stator current and moving part magnetic flux vectors is maintained mutually perpendicular to maximize force of the machine. To achieve prescribed speed response during forced dynamics control derived control law requires the external force information, which is obtained from observer. The observer outputs are position, speed, acceleration and external force, which can be exploited for both control techniques and also for diagnostic purpose. Simulations and preliminary experimental results confirm the intended performance of the drive.
