Real-time identification of the friction coefficient of a rolling guided high dynamic linear motor

The paper presents forced dynamics control of an electric drive with linear permanent magnet synchronous motor. This control method offers an accurate realisation of a dynamic speed response, which can be selected for given application by the user. In addition to this, the angle between stator current vector and moving part flux vector are maintained mutually perpendicular as it is in conventional vector control. To achieve prescribed speed response derived control law requires an external force information, which is obtained from the set of observers. The first set of observers is based on sliding-mode, while the second observer is classical full-state observer and exploits information of the position sensor. Simulations of the overall control system together with preliminary experimental results for the drive with rotational synchronous motor predict intended performance of the drive.
