Abstract :
Non-stationary disturbances in motion systems generally limit the closed-loop performance. If these disturbance can be measured, this measurement can be used to enable a linear parameter varying (LPV) controller to adapt itself to the current operating condition, resulting in a closed-loop system with an overall increased performance. In this paper, this idea is applied to an active vibration isolation system.
