Prescribed closed-loop speed dynamics control of the actuator employing linear permanent magnet synchronous motor

A new control method for the drives employing linear permanent magnet synchronous motor with prescribed closed-loop dynamics is presented. This control method offers an accurate realisation of dynamic speed response profile, which can be selected for given application by the user. In addition to this, the angle between stator current and rotor magnetic flux vectors can be maintained mutually perpendicular as it is in conventional vector control. The developed control system operates with position sensor. To achieve prescribed speed response derived control law requires external force information, which is obtained from the observers. Simulations of the design control system, including preliminary experimental results for the drive with rotational synchronous motor predict the intended drive performance.
