Abstract:
A departure control system using a simulated phase in a control system for driving a linear synchronous motor vehicle wherein a propulsion coil is arranged along a guideway on a ground, a field coil is provided on the vehicle so as to face the propulsion coil, a current command value I* is outputted by speed controlling means, and an output voltage is outputted to the propulsion coil by power converting means based on the current command value I* and a phase reference indicating a relative position of the field coil to the propulsion coil in the form of an electrical angle, the departure control system generating said phase reference at the time of departure of the vehicle and comprising:simulated phase reference value generating means for generating a simulated phase reference value based on said current command value I*; and simulated phase generating means for computing a simulated phase &thgr;n by adding a predetermined phase delay &thgr;d to said simulated phase reference value and outputting the simulated phase &thgr;n as said phase reference.
