ShareAnalogue adaptive vibration cancellation system for Stirling cryocoolers.
Author(s) : COLLINS S. A., FLOTOW A. H. von, PADUANO J. D.
Type of article: Article
Summary
The system uses a custom-designed multi-axis counterbalance and an analogue implementation of an adaptive feedforward compensator. A non-linearity associated with the counterbalance is modelled, and its effect on the closed-loop system is assessed. In an initial test, the third harmonic of the expander's axial force was cancelled by 22-38 decibels over a wide range of drive frequencies, with little effect on the other harmonics or the lateral vibrations.
