【Abstract】 A high-speed electric multiple unit(HSEMU) has characteristics of complex running process and dynamic environment. To ensure the safety and punctuality of HSEMU in the running process, this paper proposes an optimal control scheme for tracking and running of HSEMU combining the offline modeling and online tuning. Collecting the real running data, an ANFIS model of HSEMU running process is established and then a gradient descent algorithm is used to adjust the ANFIS model. Based on the ANFIS model, an improved generalized predictive control method is designed to realize the optimal control of HSEMU. Experiment results conducted on the real-word running data of CRH380 AL show the effectiveness of HSEMU.更多还原
