Abstract
A microprocessor based control scheme for a chopper-fed-d.c.-drive intended for the use in an electric vehicle is described in this paper. The drive consists of a thyristor chopper for the armature current and a transistor chopper for the excitation, which are both controlled by an INTEL 8031 single chip microcomputer. The simultaneous control of two real-time-processes with extremly stringent time requirements is achieved by a special program-structure. All timing is done by using the 8031's two built-in 16-bit-timer/counters, so only a small amount of external hardware is needed.
