PURPOSE:To so control a speed that an actual speed remarkably coincide with a speed command by correcting a calculating coefficient of an air resistance of a traveling resistance calculating equation in real time. CONSTITUTION:Values K1, K1+DELTAK1, K1-DELTAK1 in which a calculating coefficient K1 of an air resistance Da is different by DELTAK1 in reponse to a magnitude of a speed deviation are prepared in a traveling resistance calculating equation for calculating a traveling resistance during traveling of a train, and a suitable coefficient is selected by always comparing with a result of a simulated speed by calculating the simulated speed. Hence, the coefficient can be corrected in real time, and an accuracy of a predicted current value If to be obtained from the resistance to regulate an output current command value Iout can be improved. |
