A flight control system test result evaluation method

Abstract

The invention provides a flight control system test result evaluation method. The method comprises the following steps: synchronously applying a test excitation signal to a tested flight control system and a flight control system simulation model; recording a response output signal of the tested flight control system, and recording a response output signal of the simulation model; After performingdata smoothing or digital filtering on the response output signal of the tested flight control system, solving the spatial distance of the response output signal of the tested flight control system and the response output signal of the simulation model at the same data point; judging the matching between the response output signal of the tested flight control system and the response output signalof the simulation model; and evaluating the test result of the flight control system according to the judgment result. The method can achieve the automatic evaluation of the test result of the flightcontrol system, is accurate in evaluation result, and is high in practicability.

Description

technical field [0001] The invention relates to the technical field of aviation, in particular to a method for evaluating test results of a flight control system. Background technique [0002] In the design and development of flight control systems, it is often necessary to carry out tests at different levels, such as component-level, subsystem-level, sub-system-level and even system-level testing and verification tests, to test the functions and performance of the designed product and its component systems Whether it meets the design requirements. Such as flight control system control law transmission ratio test, time domain response test, frequency domain response test, etc. In the above tests, by applying different excitation signals to the input end of the flight control system under test, the output response of the system under test is measured and recorded. Signal, generate the graphic curve of the system output response signal, and then the test personnel analyze the...

[0003] On the one hand, the intuitive evaluation of the above test results is affected by the subjective will of the test personnel such as engineering experience and theoretical level. On the other hand, only individual feature points are used to judge, resulting in large random differences in evaluation. , different experimenters often come to different conclusions
