Abstract :
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 jω-axis zeros. A 4-step gain SAC design procedure and an example are presented
