Embodiment 1

[0102] A specific embodiment of the present invention discloses a kind of evaluation system of semi-physical simulation test under no benchmark condition, such as figure 1 As shown, it includes a simulation data acquisition module, a single-variable uncertainty calculation module, a comprehensive uncertainty calculation module, and an evaluation result judgment module connected in sequence.

[0103] The simulation data acquisition module is used to receive the simulation data of all uncertainty output variables in multiple semi-physical simulation tests under the same test condition, and send them to the single variable uncertainty calculation module.

[0104] The univariate uncertainty calculation module is used to construct the data distribution probability envelope of each uncertainty output variable based on the obtained simulation data, and then determine the random uncertainty and probability variance of each uncertainty output variable. The degree of certainty is sent t...

Embodiment 2

[0110] The optimization is carried out on the basis of Example 1, and the hardware-in-the-loop simulation test is an aircraft hardware-in-the-loop simulation test. The evaluation system is used for aircraft hardware-in-the-loop simulation tests, or other types of hardware-in-the-loop simulation tests.

[0111] For the hardware-in-the-loop simulation test of the aircraft, the uncertainty output variables include at least one of landing point deviation, attitude, angle of attack and sideslip angle, position, velocity, and the like.

[0112] Specifically, the landing point deviation is the deviation between the landing point position of the aircraft obtained from the hardware-in-the-loop simulation test and the target position. Aircraft attitude includes pitch angle, yaw angle, roll angle, etc.; aircraft position includes altitude, lateral, and longitudinal positions. For simplicity of calculation, the attitude and position of the aircraft at the landing point of each hardware-i...

Abstract

The invention relates to an evaluation system for a semi-physical simulation test under a non-reference condition, belongs to the technical field of simulation evaluation, and solves the problem thatthe effect of the semi-physical simulation test cannot be accurately evaluated in the prior art. The system comprises a simulation data acquisition module used for receiving simulation data of all uncertainty output variables of multiple semi-physical simulation tests under the same test condition; the univariate uncertainty resolving module is used for constructing a data distribution probabilityenvelope of each output variable according to the simulation data so as to determine the random uncertainty and the probability uncertainty of each output variable; the comprehensive uncertainty resolving module is used for constructing a comprehensive uncertainty vector of the whole semi-physical simulation test according to the random uncertainty and the probability uncertainty, determining a weight coefficient of each element in the vector, and performing weighted averaging to obtain a comprehensive uncertainty measurement value; and the evaluation result judgment module is used for judging whether the semi-physical simulation test result is credible or not according to the comprehensive uncertainty measurement value.

Description

technical field [0001] The invention relates to the technical field of simulation evaluation, in particular to an evaluation system for semi-physical simulation tests under no reference conditions. Background technique [0002] During the hardware-in-the-loop simulation test, due to errors in the simulation equipment such as the simulation turntable, target simulator, load simulator, area array, altimeter simulator, etc., the accuracy of the entire simulation test is affected, which in turn affects the confidence of the simulation results. [0003] At present, in the existing technology, the uncertainty of hardware-in-the-loop simulation experiments without benchmark data is usually measured by standard deviation, but the standard deviation is sensitive to the sample size and has dimensions, and the uncertainties given by different sample sizes There are great differences in the performance measurement results, and it is inconvenient to judge how big is bad and how small is ...
