AUTOMATIC CONTROL OF AMORPHOUS BANDS REELING SYSTEM

Václav Kalaš

   The contribution is oriented to the area of automatic control of the reeling of amorphous bands. The bands are produced by the technology of fast cooling. The process of bands production runs at velocities of approx. 30 m/s. In the article an original method is presented to capture the band beginning into a special reeling device that is automatically controlled. This method is patented by the author. The problem is in extremely difficult control of the abducting forces in the variable structure system with variable parameters. tensile forces generator, current and velocity servosystem,

Keywords: non-stationary moment of inertia, variable conversion ratio, dynamical torques, control computer, the principle of invariance
