Because of the disturbance of operation environment in mass rapid transit (MRT) system, the robustness against disturbance and the schedule punctuality under control constraint are important issues to be considered in designing Automatic Train Regulation (ATR) for MRT system. In this paper, the study on suitable traffic model for designing ATR system and ATR design based on adaptive critic design (ACD) of approximated dynamic programming, specifically on dual heuristic programming (DHP) are presented. Moreover, the method to deal with control constraint and applying gain scheduling to deal with the time variant environment of MRT system are addressed as well. For comparison, simulations with real operation environment data are done for ATRs designed by both adaptive critic method and LQ optimization method.
