The UAV Landing Quality Evaluation Research Based on Combined Weight and VIKOR Algorithm

This paper aims to use the VIKOR method to evaluate the landing quality of unmanned aerial vehicle (UAV) based on flight parameters, determining the parameter interval of the landing quality classification. At present, the evaluation of UAV landing quality mainly depends on experts’ experience or single parameter exceeding the limit, whose results are inevitably lack of scientific and objectivity. In order to improve this problem, we evaluated the landing quality with multiple flight parameters, and determined the absolute criteria using the resulting ranking. Firstly, analyzed the influence of flight parameters on the landing quality, and determined the decision matrix. Secondly, use the combination weighting method consisting of the precedence chart method and the entropy weight method to determine the weights. Moreover, VIKOR was selected as the method, whose results was given by comprehensive evaluation with sorts of flight parameters. And then we took the original data that landing sorties was in the top 20% VIKOR ranking and determined the absolute criteria for UAV landing quality evaluation. Finally, compared the evaluation results of the TOPSIS and VIKOR, it can be known that there is a high similarity between TOPSIS and VIKOR ranking with correlation coefficient 0.917, but the VIKOR method is better in UAV landing quality evaluation.
