Axial compressor and control method thereof to stabilize fluid

A fluid stabilizing control method of an axial compressor comprising a casing and an axial impeller that compresses a fluid through being rotated in the casing, the control method comprising:

• driving to drive the axial impeller;
• and
• stall controlling to suppress or prevent an occurrence of a stall that may transpire during rotation of the axial impeller by supplying compressed air into the casing through a stall controller according to a predetermined time and volume,
• wherein, in the stall controlling, the stall controller comprises a pulsator configured to inject the highly-pressurized compressed air into the casing by a pulsed injection method before the axial impeller goes into an unstable region during driving.
