The Optimal Coupling Matrix of Stochastic Resonance in Multi-Machine Traction

In railway transport, stochastic resonance (SR) and some phenomena may happen when multi-machine traction system is hauling a sequence of carriages. These phenomena may vary with the coupling coefficients among these traction machines. To work together fluently and produce the maximum output, energy changes and maximum output of this system can be worked out with the power spectrum of the coupling system. Genetic algorithm can be used to search for the best coupling matrix so as different traction machines can work fluently and efficiently as a whole.
