Reducing travel energy costs for a subway train via fuzzy logic controls

摘要

Train controls at the Montreal Subway are revisited. A simulation environment is developed and used to analyze the desirability of replacing present (PID based) controls by fuzzy logic controllers which consume less energy. Two fuzzy logic controllers are proposed: the first one turned out to produce practically no improvement, but the second one achieved an average of 6% energy savings while slightly reducing the average train travelling time from present levels.
