The control and monitor system based on a microcomputer was composed according to the conceptual design for EPEX system and successfully operated the repetitive discharges of 3 million shots in a net operation period of 25 days, although the hardware of the control and monitor system was composed of equipment for general ground use. The successfull operation verified basic control logics for a magnetoplasmadynamic (MPD) propulsion system. Based on the test results, the conceptual design or requirements for the control and monitor subsystem for EPEX was refined. The monitor signals were evaluated and selected for the flight system.
