Research of selective control robust properties of the rotor position in the electromagnetic suspension

Abstract

Selective automatic control system of horizontally oriented rotor position in elastic supports is considered. Simulation results of system operation with a wide range of rotation speed and in the different modes - smooth start, normal operation mode, external and internal (vibration) disturbances, rotor overrun, emergency stop - are presented. Advantages of a selective approach to control of non-linear object ≪electromagnet-rotor≫ are justified. In conclusion robust features of designed control algorithm are proved.
