| Abstract |
In Communication‐Based Train Control (CBTC)
systems, random transmission delays and packet drops
are inevitable in the wireless networks, which could
result in unnecessary traction, brakes or even emergency
brakes of trains, losses of line capacity and passenger
dissatisfaction. This paper applies predictive function
control technology with a mixed H /H 2 control
approach to improve the control performances. The
controller is in the state feedback form and satisfies the
requirement of quadratic input and state constraints. A
linear matrix inequality (LMI) approach is developed to
solve the control problem. The proposed method
attenuates disturbances by incorporating H /H 2 into
the control scheme. The control command from the
automatic train operation (ATO) is included in the
reward function to optimize the train’s running profile.
The influence of transmission delays and packet drops is
alleviated through improving the performances of the
controller. Simulation results show that the method is
effective to improve the performances and robustness of
CBTC systems. |
