[0153] Example
[0154] In the present embodiment, the experiment simulated the controlled object unit as set forth in section shift multiple material point model of the train, the train of the total mass of 840T, which is the maximum operating speed of 350km / h, the automatic train protection speed of 360km / h , basic resistance selection parameters a, b and c are a = 0.53, b = 0.0039, c = 0.000114, then learning algorithm written in Matlab 2.1 simulation program, the desired speed simulation total 2000 sample points, one in the system is configured to CORE i7, memory to run programs on the computer 8GB, results Image 6 , Figure 7 , Figure 8 with Figure 9 , The actual speed and the actual distance of the train can well track the given desired distance and the desired speed, the desired speed and the desired speed and the actual distance curve and the actual curve from the two kinds of curve few exceptions point substantially coincide, the speed error curve substantially near z...
