Vibration control of flexible structures with close modes using adaptive inverse control method

The vibration control of space flexible structures is difficult as they are with close models and their structural parameters can be easily affected by complex space environments.It is valuable to study the adaptive inverse control.Here,multi-variable adaptive inverse control was successfully applied to a 2-D flexible plate test system with close modes,and good experiment results were obtained.Persistent disturbances were suppressed effectively.When the structural parameters changed,the procedures of online identification and controller parameter adaptive adjustment restarted and effective vibration suppression was realized again.
