Abstract:

An active stall avoidance system was designed comprising a stall recovery controller a nonlinear compressor operating point controller and a scheme for switching between these two. Different control schemes with respect to stall removal and switching have been developed and implemented on a real- time computer. The systems capability of successful stabilization of a stalled compressor with respect to performance loss was demonstrated by several experiments conducted on a low-speed axial compressor stage. The experiments were analyzed in detail and governing parameters of stall recovery and performance are identified. Finally improvements for the control scheme are suggested.
