Abstract

Blades Compressors Design engineering Pressure control Steady-state Surges Valves Virtual colonoscopy Control Systems Recycling
This paper presents a surge avoidance controller (SAC) for compressor systems operating near maximum pressure. The main result is a SAC structure characterized as an affine state-feedback control law in terms of the surge line and a directional parameter. This paper shows that with this new SAC characterization combined with existing compressor models, the existence of performance limiting j/spl omega/-axis zeros. A 4-step gain SAC design procedure and an example are presented.
