Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of unmanned swarm and the technical field of simulation evaluation, and particularly relates to a numerical-real combined simulation evaluation method and device for performance of an unmanned swarm. BACKGROUND

[0002] With the rapid development of unmanned technology, unmanned swarms are increasingly widely used in fields such as logistics, exploration and resource management. Performance evaluation of unmanned swarms, as a key link to ensure their efficient and reliable operation, has attracted much attention from researchers and industry practitioners. Currently, performance evaluation of unmanned swarms mainly adopts separate actual testing or simulation testing methods. Although actual testing alone can truly reflect the performance of unmanned swarms in actual scenarios, it has problems such as high testing cost, long testing cycle, great influence of environmental factors and difficulty in reproducing testing conditions. While simulation testing alone has advantages such as low cost, strong repeatability and flexible setting of testing scenarios, the accuracy and reliability of simulation testing results are difficult to guarantee due to the differences between simulation models and actual scenarios. In addition, existing evaluation methods often ignore the correlation between actual testing results and simulation testing results, and fail to fully utilize the complementarity of the two, making the evaluation results unable to comprehensively and accurately reflect the true performance of unmanned swarms.

[0087] performing eigenvalue solving processing on the difference matrix to obtain an average eigenvalue λ0 and a maximum eigenvalue λ max ;

[0088] respectively, to obtain a transformation matrix Y; a row vector of the transformation matrix Y is a variational modal decomposition result of each row vector of the difference matrix;

[0089] performing fusion feature calculation on the transformation matrix and the difference matrix to obtain a fusion matrix A;

[0090] performing logarithmic calculation processing on diagonal elements of the fusion matrix A to obtain a measured performance evaluation value.

[0091] An expression of the logarithmic calculation processing is:

[0092]

[0093] wherein, A i is an i th diagonal element of the fusion matrix A, M is a number of diagonal elements, and sc is the measured performance evaluation value.

[0094] An expression of the fusion feature calculation is:

[0095] A=YΔ T R0,

[0096] wherein, a singular value decomposition expression of the difference matrix C is C=WΔV, W, Δ, and V represent a left matrix, a middle matrix, and a right matrix of singular value decomposition of the difference matrix C respectively, and R0 is a cross-correlation matrix of the transformation matrix, and is obtained by performing cross-correlation calculation on row vectors of the transformation matrix;

The variational modal decomposition decomposes the row vectors of the difference matrix into different modes, deeply mines the multi-scale features of data, and provides more abundant information for subsequent analysis. Through the fusion feature calculation expression, the transformation matrix Y is combined with the singular value decomposition result of the difference matrix and the cross-correlation matrix R0 of the transformation matrix, so that the information of different dimensions of the matrices is fully utilized, and the fusion matrix A can comprehensively reflect the multiple characteristics of the difference between the actual test result and the standard value.

[0104] Wherein, α i , β i , λ i are the mean, variance and median values of the i-th row vector of the difference matrix, and M1 is the row dimension of the difference matrix.

[0105] In terms of statistical fluctuation estimation, the mean, variance and median values of each row vector of the difference matrix are first statistically obtained, which respectively describes the data from the three dimensions of central tendency, dispersion degree and data distribution position, and comprehensively captures the fluctuation characteristics of the data. The fusion statistical fluctuation processing expression combines trigonometric functions and exponential functions to nonlinearly fuse the mean, variance and median values of different row vectors, which can effectively amplify the differences in data fluctuations and more accurately quantify the statistical fluctuation of the performance of the unmanned cluster in different indicators, providing a reliable basis for subsequent simulation performance evaluation based on statistical fluctuation values, and further improving the stability and accuracy of the overall performance evaluation of the unmanned cluster.

[0106] The data cleaning processing includes filling missing values, smoothing noise data, smoothing or deleting outlier points; the smoothing of noise data is to first identify noise data, and then smooth the noise data according to the data before and after the noise data; the noise data is a value less than the detection sensitivity of the sensor of the observation data or greater than the measurement upper limit of the sensor of the observation data. The identification of the outlier point can use the Kalman filter method. For the determination of the filling value of the missing value, the measurement values within a certain sampling interval before and after the missing value can be averaged.

[0107] The category detection processing is to determine whether the data category of each element in the test data sequence of each performance indicator of the first information set is consistent with the preset data category, and to delete the inconsistent data from the test data sequence of the performance indicator to obtain a second information set.

[0108] The simulation performance evaluation value is obtained by performing simulation performance evaluation processing on the performance simulation test result information set and the index standard value set in the pretreatment information set based on the statistical fluctuation value, and the simulation performance evaluation value comprises:

[0109] The simulation test result value sequence of each performance index in the performance simulation test result information set in the pretreatment information set is subtracted from the standard value of the corresponding performance index in the index standard value set, so that a corresponding simulation difference value sequence is obtained.

[0110] Difference estimation calculation is performed on all simulation difference value sequences, so that a simulation performance evaluation value cy is obtained.

[0111] The expression of the difference estimation calculation is as follows:

[0112]

[0113] Wherein, a ij is the jth element of the simulation difference value sequence of the ith performance index, b ij is the jth element of the simulation test result value sequence of the ith performance index in the performance simulation test result information set in the pretreatment information set, and N1 and M2 are the element number of the simulation test result value sequence and the total number of performance indexes, respectively.
