Abstract

This invention discloses a method for suppressing unsteady pressure pulsations in an air intake based on deep reinforcement learning, relating to the field of flow control technology. This invention utilizes real-time interaction and online learning between a deep reinforcement learning agent and a high-fidelity CFD environment. By designing a composite reward function with adaptive weighting factors and a rigorous physical constraint system, the controller can dynamically perceive the flow field state and automatically adjust the control objective and intensity. This achieves efficient and robust pressure pulsation suppression under a wide range of operating conditions, significantly improving the control's adaptability, response speed, and final suppression effect, while ensuring the safety and engineering feasibility of the control process.
