摘要
文章提出了一个针对于混杂系统的主动容错架构。通过对混杂系统的模型抽象,实现混杂系统到离散事件系统的转化。根据离散事件系统的允许事件轨迹计算其安全可控事件集合,进而合成主动容错监控器,实现混杂系统的主动容错控制。最后,以列车运行控制系统车载设备为例,实现列控系统车载监控器的合成。系统仿真结果证明了合成监控器的有效性。
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.
