Internal rotation type air inlet channel boundary layer self-adaptive suction regulation and control system and method

The invention provides a self-adaptive suction regulation and control system and method for a boundary layer of an inward rotation type air inlet channel, and belongs to the technical field of inward rotation type air inlet channel intelligent regulation and control. The self-adaptive suction regulation and control system comprises a main controller which is used for obtaining a high/low level and a PWM signal through an external environment feedback value and outputting the high/low level and the PWM signal through a TD3 intelligent agent deployed on an FPGA development board; the network weight and bias are adjusted according to the size data of the separation bubbles, the total pressure recovery coefficient and the flow coefficient; and the execution/feedback subsystem is used for correspondingly controlling the opening and closing of the suction channel and the suction pressure of the suction hole one by one according to the high/low level and the PWM signal, and sending the obtained separation bubble siz
