Abstract
PURPOSE: To improve the rise-up performance of an electric brake by providing delaying circuit in a brake-control circuit of an electric-car-control system which utilizes both the electric brake and an air brake.
CONSTITUTION: A capacitor 15 is connected to a brake-control circuit LMT in an electric-car-control system which gives control commands to a current control circuit 7 depending on the deviations of command patterns Ip, mortor currents IM and braking commands IF and which controls ON and OFF of a chopper of a chopper by an output signal e. Siad capacitor 15 is connected to a resistor 12 to give a factor of primary delay to the input and output responses of an operation amplifier 10. In this constitution, since the brake control circuit LMT is not instantaneously operated immediately after the current has risen up by the braking commands, the current-conduction-rate command which is the output signal from the current control circuit 7 becomes sufficiently large even though the input deviation Ip-IM is small, and the braking current can be readily risen up.
