Abstract:   (1697 Views)
This study is concerned with the real-time delay recovery problem in metro loop lines. Metro is the backbone of public transportation system in large cities. A discrete event model for traffic system of metro loop lines is derived and presented. Two effective automatic controllers, linear quadratic regulator (LQR) and model predictive controller (MPC), are used to recover train delays. A newly-designed real-time algorithms for constrained LQR and constrained MPC in the presence of operational constraint on control actions is introduced. MPC and LQR automatic controllers are compared for traffic regulation in metro loop lines. To facilitate fair comparison of the performance of the automatic controllers, different scenarios are considered. The results are then compared to determine the relative effectiveness of the controllers.
