The invention provides an asymmetrical wedge-shaped vortex generator applied to flow control over a compressor cascade and a design method thereof. The structure of the wedge-shaped vortex generator is redesigned, the dimension of the vortex generator which controls the branch side of a suction surface is decreased as far as possible, so that the form drag loss and the gas flow separation on the suction surface side are effectively reduced, and the problem that the capacity of lowering the flow loss of a compressor of the wedge-shaped vortex generator is not high is solved. The asymmetrical wedge-shaped vortex generator is introduced, so that suction surface vortexes and pressure surface vortexes are induced to be generated, the structure and transverse flowing of channel vortexes are changed through low-energy fluid rolling an adsorption side layer, gas flow separation on the suction surface/an end wall corner area is reduced, and therefore the total pressure loss of the compressor cascade is lowered.
