Abstract :
This paper discusses a new method to increase the stable operating range of a compressor operating in the presence of large total pressure inlet distortion by using low-bandwidth actuators. A stabilization criterion is defined and an algorithm for finding the optimal control law is presented. Practical issues related to the implementation of the ideal distributed actuators are discussed and additional results are presented for currently available actuators.
