SWITCHING SPEED-GRADIENT CONTROL OF PASSAGE THROUGH RESONANCE FOR THE TWO-ROTOR VIBRATION UNIT

The switching control algorithm for passing through resonance zone for the two-rotor vibration unit is proposed. The algorithm is based on speed-gradient method and leads to the significant reduction of the required level of the controlling torque. The dynamics of the overall hybrid system and its robustness against changes of spring stiffness, excentricity of rotors and damping is analyzed by computer simulation. Copyright © 2007 IFAC
