Under the premise of a rotor system satisfying the quasi steady-state condition, the influencing coefficient method based on the steady-state rotor balancing is extended to single-plane or multiple-plane gain-scheduling control of a rotor with slowly varying speed and all factors affecting the stability of a gain-scheduling control are analyzed. Numerical simulations verify that the gain scheduling control can effectively suppress imbalance-induced vibration of a rotor with slowly varying speed.
