Abstract
In this paper the modelling and feedback control of non-contact ultrasonic squeeze film levitation bearings are presented. Simple models are employed to describe the levitation effect in order to make it accessible to a wide range of applications. The ultrasonic transducer acts as the dominating lag element in the ultrasonic levitation system. Thus the transient behavior of the ultrasonic transducer is investigated by averaging method in order to analyse the dynamic behavior. Finally the design of the overall feedback control system is presented. This is applied to a linear squeeze film levitation bearing. For the system at hand the theoretical model is validated experimentally. It turns out that the theoretical model is in good agreement with the obtained experimental results.
