switching control in active vibration isolation

Nathan van de Wouw, marcel heertjes, maurice heemels
In this paper, a switching control approach is studied with
applications to active vibration isolation. The control design is based on the concept of input-to-state stability of the resulting discontinuous feedback system with respect to disturbances. The switching control strategy demonstrates improved disturbance rejection under feedback combined with a small sensitivity to noise in the absence of such feedback. Herein the control effort needed to achieve improved performance is substantially reduced. To access the performance of the closed-loop system, the control scheme is tested on a commercially available isolation system.
