摘要：
In response to the the requirements of high control precision and high robustness of medium-speed maglev train operation control system, a fractional order PID-based operation control method was proposed in this paper. Firstly, based on medium-speed maglev train operation data, a particle swarm optimization-simulated annealing algorithm was used to identify the coefficients of train air resistance and improve the accuracy of train dynamic model. Secondly, a fractional order PID velocity controller was designed to track the target speed curve of the train and reduce the influence of various running resistances on the train operation process. Finally, based on the test line data, the train operation performance under fractional order PID and integer order PID control was simulated and compared. The simulation results show that the proposed operation control algorithm can effectively improve the speed operation control performance of the train and meet the requirements of medium-speed maglev transportation for train operation control. © 2022, Department of Journal of the China Railway Society.
