Embodiment Construction
[0027] The present invention will be further described below in combination with specific embodiments.
[0028] Step 1 establishes the EMU multi-agent system model:
[0029] First, the force analysis of each car of the EMU is carried out, and the following dynamic model is obtained:
[0030]
[0031] In the formula, i is the number of carriages, m i is the mass of the carriage, x i ,v i Represent the running speed and displacement of the i-th car respectively; u i (t) is the control input of the i-th carriage;
[0032] d i is the uncertain external disturbance received by the i-th carriage, a 1i 、a 2i 、a 3i are the constant items in the running resistance formula, d r 、d c 、d t are the additional resistance of the tunnel, ramp and bend, respectively, and their expressions are
[0033] f i ( ) is the nonlinear coupling force of the i-th car, which comes from the adjacent car, k 0i =80000N / m, ε=-0.5, the spring under this parameter model is a typical hardening-S...
