Self-learning based centrifugal compressor surge mapping with computationally efficient adaptive asymmetric support vector machine

Xin Wu, Auteur ; Yaoyu Li, Auteur |

Dans Transactions of the ASME . Journal of dynamic systems, measurement, and control (Vol. 134 N° 5, Septembre 2012)

When an air compressor is operated at very low flow rate for a given discharge pressure, surge may occur, resulting in large oscillations in pressure and flow in the compressor. To prevent the damage of the compressor, on account of surge, the c[...]
