Abstract

The embodiment of the invention discloses an unmanned aerial vehicle mathematical model proofreading method and device, equipment and a storage medium, and the method comprises the steps: setting input sets of three calibration steps to be a full constant value, a single waveform value and a full waveform value, and judging whether a difference value between a calibration output set and a comparison output set is greater than a preset threshold value or not; calibrating the mathematical model to be calibrated step by step in a mode of adjusting the related model parameters of the output physical quantity greater than the preset threshold value, so the difficulty and workload of finding out modeling errors by modeling technicians are reduced, the problem that the design precision of the unmanned aerial vehicle is low due to the fact that a mathematical model is large in volume and the correctness and accuracy are difficult to guarantee is solved, the modeling precision is improved, and a foundation is laid for a subsequent unmanned aerial vehicle control law design link.

Description

technical field [0001] The present application relates to the field of aircraft modeling, in particular to a method, device, equipment and storage medium for proofreading a mathematical model of an unmanned aerial vehicle. Background technique [0002] The establishment of the mathematical model of the controlled object is the basis for the design of UAV flight control laws and simulation experiments. In the process of establishing the controlled object model and flight control law design, it is necessary to proofread the model to ensure the correctness of the previous mathematical model and to facilitate the subsequent control law design work. [0003] For UAVs with high modeling accuracy requirements, especially UAVs with large envelope and multiple control surfaces, the range of state variables is large, the coupling of control surfaces, aerodynamic and dynamic characteristics are complex, wind tunnel data and engine The power models are all in the form of multi-dimensio...
