The author carried out research on plasma flow control of axial-flow compressor earlier in the world. After nearly a decade of research, the author established a deep understanding of the plasma flow control of axial-flow compressor. In this paper, some advances of plasma flow control of axial-flow compressor are briefly introduced. The compressor cascade is taken as the research object. The law and mechanism of the plasma leakage inhibition on the tip leakage flow are analyzed. By numerical simulation and experiments, The flow control law and mechanism of plasma excitation for high load axial compressor stall were studied. The high pressure compressor cascade was taken as the research object to explore the flow control Then the concept of plasma-activated compressor is introduced. Finally, the prospect of future research work is given.
