Abstract

The invention is applicable to the technical field of wind tunnel tests, and provides a wind tunnel test scheduling method and system based on deep reinforcement learning. In the wind tunnel test scheduling method and system, the utilization rate of the branch pipeline and the valve opening delay time of the branch pipeline are considered, wherein one variable of the target function is the utilization rate of the branch pipeline, therefore, the distribution of the wind tunnel test scheduling pipelines can be globally considered; in the distribution, the selection of the next execution action is obtained by maximizing the target function, so that the scheduling method has predictability, the utilization rate of power resources can be maximized, the opening/closing times of branch pipelinescan be minimized, and the loss of power equipment is reduced; and the other variable of the target function is the valve opening delay time of the branch pipeline, so that the prediction accuracy canbe improved, and the smooth experiment can be ensured.

Description

technical field [0001] The invention belongs to the technical field of wind tunnel tests, and in particular relates to a wind tunnel test scheduling method and system based on deep reinforcement learning. Background technique [0002] The wind tunnel test is to fix the aircraft model or physical object in a pipe-shaped ground artificial environment (ie wind tunnel), according to the principle of relativity of motion, artificially create air flow to simulate the various complexities of aircraft or other objects in the air. An aerodynamic experimental method for obtaining experimental data to understand the aerodynamic characteristics of actual aircraft or other objects. [0003] The scheduling problem is usually defined as the problem of correspondingly allocating a set of resources in order to complete a set of work within a period of time. It exists widely in the fields of energy, transportation, production, computing, emergency medical care, security, etc. Optimization. ...
