Abstract

PURPOSE: To improve comfortableness to drive the rolling stock car when change- over to coasting running is to be performed by a method wherein the current value of an electric current pattern is reduced according to the prescribed time constant when a coasting running command is imputted, and the current value is returned to the original value according to the prescribed time constant when the coasting running command is canceled.
CONSTITUTION: A phase difference detector 14 outputs the phase difference 15 between a frequency pattern 41 and a position signal 4, and a phase compensator 16 inputs the phase difference 15 to outputs a current peack value. The maximum value of the current peak value is limited by a limiter 17 to form a current peak value pattern 19 via a current peak value pattern regulating part 20. When the coasting running command C is afforded, the current peak value pattern regulating part 20 makes the current peak value pattern 19 to be reduced according to the prescribed time constant, and when the coasting running command C is canceled, it is increased according to the prescribed time constant. The current peak value pattern 19 is multiplied by a current wave form pattern 12 to form a current pattern 5.
