Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] see figure 1 As shown, a parameter characterization method applied to the flight state of the aircraft shown in this embodiment is implemented by a computer program, mainly based on the gray correlation degree analysis method in the gray system theory to complete the mapping relationship between the flight state and the flight parameters . Using the fuzzy information entropy method, the calculation of the information entropy of the eigenvector is completed, and the mapping relation value between the flight state and the corresponding parameters is completed, which specifically includes the following steps:

[0015] Step 1, take all the collected flight parameters about the performance state of the aircraft as the base set M.

[0016] Step 2, take all the flight states as the flight state set N, and establish the mapping relationship b...

Abstract

The invention discloses a parameter characterization method applied to a flight state of an aircraft, and the method includes the following program steps of step 1, using all the collected flight parameters about the performance status of the aircraft as a cardinality set; step 2, taking all the flight status as a flight status set, and establishing a mapping relationship between the flight statusset and the cardinality set; step 3, using a gray correlation analysis method of gray system theory to calculate gray correlation values between the flight status set and the cardinality set; step 4,combining the obtained multiple groups of gray correlation values into a feature vector; step 5, calculating the fuzzy information entropy of the feature vector; and step 6, regarding the calculatedfuzzy information entropy as the mapping relationship value between the flight status and the corresponding flight parameters, and determining the optimal flight parameter corresponding to the flightstatus according to the magnitude of the mapping relationship value.

Description

technical field [0001] The invention belongs to the application field of system test methods, and in particular relates to a parameter characterization method applied to the flight state of an aircraft. Background technique [0002] During the entire flight process, the aircraft will have many kinds of flight attitudes, such as climbing after taking off from the runway, level flight to a certain height, turning when encountering strong air currents and descending after reaching the destination, etc., which are very important for monitoring aircraft performance. In terms of flight status, different flight status may require different flight parameters. For example, in the climbing phase, the parameters that need to be paid attention to will be parameters such as A, B, and C. However, when turning, the parameters that need to be paid attention to may become D, E , F and other parameters, according to the determined monitoring parameters, the accurate monitoring of the aircraft...
