This paper puts forward to a new speed control method for the rapid development high-speed railway system. It receive information from track circuit, supervision speed curve, transponder and etc,deduce and calculate the speed value of dynamic expected, and calculate the real-time error. Then the closed-loop speed control system is used to realize the real-time control based on a multi-modal intelligent control algorithm that has been designed according to the real-time error. And make a simulation system to value it. The result shows it has good dynamic performance and reliable steady-state property. It is really a useful method to provide a advanced way for the train safer, faster and more comfort.
