Abstract :
A new 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 nonlinear system and its robustness against changes of spring stiffness, excentricity of rotors, damping and unmodelled dynamics of the platform inclination angle is analyzed by computer simulation.
