| Abstract: | An active fault tolerant framework of Hybrid System was presented in this paper. By discreting abstraction of the Hybrid System, the transformation of Hybrid System to Discrete Event System （DES） was obtained. Then a set of safe controllable events was calculated with respect to the discrete event trajectories. By using of the safe controllable event, the active fault tolerant supervisor was synthesized. Finally, the supervisor of on-board equipment in Train Control System was synthesized, and the effectiveness of the proposed active fault tolerant algorithm was validated and demonstrated by the simulation results. |
