Method for maximising the slip-dependent frictional force which occurs in the case of surfaces rubbing on each other under the influence of force, using a fuzzy controller

By means of the invention, a method is described for maximising a frictional force transmitted in, for example, wheel-rail systems. In contrast to previously common methods, a variable magnitude of correction is used here. This has the advantage that, after an impressed disturbance, operation at the...

Zusammenfassung:	By means of the invention, a method is described for maximising a frictional force transmitted in, for example, wheel-rail systems. In contrast to previously common methods, a variable magnitude of correction is used here. This has the advantage that, after an impressed disturbance, operation at the maximum frictional value of the frictional value curve can be achieved once again very rapidly. A further advantage is achieved by taking into account the different impression of frictional value curves in the case of different wheel-rail pairings by means of a matched selection of the membership functions of the fuzzy controller.
