Abstract
The present invention relates to a kind of flight control system normally work the acquisition methods of criterion, for the checking of flight control system environmental test.The present invention provides the acquisition methods that a kind of flight control system normally works criterion, standardization work criterion acquisition methods is learning system work criterion under the input of system difference, different modalities and working environment, and verifies whether flight control system functional performance in various environmental tests meets System Technical Specification requirement with this.By to " work criterion learn " appraisal procedure of flight control system output order value and estimation flow, obtaining with fixing flow process and signal standards difference demand and fly to control work criterion, it is achieved the concordance that holonomic system criterion obtains；The instruction output valve that system work is the most easily affected by input is weighed by the method for variance, by differentiating the dispersion degree of different output order collection value and whether meeting this signal feeding variance yields for mark, determine whether system work criterion can be as the work criterion of multiple output system.
Description
Technical field
The present invention relates to a kind of flight control system normally work the acquisition methods of criterion, for testing of flight control system environmental test
Card.
Background technology
Civil aircraft flight control system is the complication system of a multiple-input and multiple-output, and the checking of simultaneity factor high security requires system
Steady operation under various working environments, and functional criterion requirement to be met.Owing to flight control system output signal can not be kept away
From to various discrete analog(ue) inputs, system mode and various electromagnetism or the impact of working environment, fly under the conditions of different operating
The acquisition of Ore-controlling Role work criterion is a difficult problem.Need one standardization work criterion acquisition methods to input in system difference,
Learning system work criterion under different modalities and working environment, and verify flight control system merit in various environmental tests with this
Performance whether can meet System Technical Specification requirement.
Summary of the invention
The technical problem to be solved is: provide the acquisition methods that a kind of flight control system normally works criterion, pin
To difference input, different modalities and different operating environment, the real-time criterion meeting flight control system obtains demand.
The flight control system of the present invention normally works the acquisition methods of criterion, comprises the following steps:
Step one, flight control system power on, it is judged that whether the discrete input and output of system and system Working mould state value meet sets
Value, when meeting perform step 2, no if continue executing with step one；
Step 2, the work criterion study of beginning system output order value
Being acquired system output value, 100 system output value of continuous acquisition, according to the system output value meter collected
Calculate meansigma methods, then calculate the system output value standard variance stdDev relative to meansigma methods, if standard variance stdDev >=
Set requirement, then return step 2；If standard variance stdDev < set requirement, record system simulation and discrete criterion value, complete
Become learning process.
Beneficial effects of the present invention: by " work criterion learn " appraisal procedure of flight control system output order value with comment
Estimate flow process, obtain with fixing flow process and signal standards difference demand fly control work criterion, it is achieved flight control system difference input,
The concordance that holonomic system criterion under different modalities and working environment obtains；System work is weighed by the method for variance
Make the instruction output valve the most easily affected by input, by differentiating the dispersion degree of different output order collection value and whether meeting
This signal feeding variance yields is mark, determines that the system work criterion exporting acquisition now by extraction system in real time is the most permissible
As the work criterion of multiple output system,
Accompanying drawing explanation
Fig. 1 is that the present invention normally works the flow chart of criterion acquisition methods.
Detailed description of the invention
A kind of flight control system normally works the acquisition methods of criterion, comprises the following steps:
Step one, flight control system power on, it is judged that whether the discrete input and output of system and system Working mould state value meet sets
Value, when meeting perform step 2, no if continue executing with step one；
Step 2, the work criterion study of beginning system output order value
Being acquired system output value, 100 system output value of continuous acquisition, according to the system output value meter collected
Calculate meansigma methods, then calculate the system output value standard variance stdDev relative to meansigma methods, if standard variance stdDev >=
Set requirement, then return step 2；If standard variance stdDev < set requirement, record system simulation and discrete criterion value, complete
Become learning process.
