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.

Firstly, based on the sliding mode control and backstepping technique, a new attitude tracking controller is derived to control the attitude motion of spacecraft, the stability of the system is analyzed via Lyapunov method and the reaction wheel dynamics is also considered from the real applications point of view. The whole design process is divided into two steps: the first step is to use sliding control technique to design suppositional adaptive variable structure controller; and the second step is to design attitude tracking controller based on SMC and backstepping technique. Numerical simulations are performed to show that both tracking maneuver and vibration suppression can be accomplished effectively.
