Embodiment Construction

[0048] Specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0049] 1. Module design

[0050] The process control module 1, the environment simulation module 2 and the background processing module 3 can be dynamically loaded onto the digital simulation platform to run, and the digital simulation platform is a platform that can provide memory access and operation control interfaces, such as Keil51 and Vtest and other products. The virtual CPU is a part of the digital simulation platform. The off-line analysis module 4 processes the output data after the test process ends, analyzes the flight control software from the frequency domain, and outputs the test analysis results.

Abstract

The invention relates to frequency domain test system and method for a flight control software control network, which can realize a frequency domain test to a flight control software control network. The invention is characterized by loading a process control module, an environment simulation module and a background processing module to a digital simulation platform for testing, so that the test of the flight control network is realized, and then, the frequency domain output by the test is analyzed by an off-line analysis module, wherein the process control module is used for controlling the whole process of the test, and the environment simulation module and the background processing module are used for simulating the real-time flight environment of the flight control software and generating and recording input and output data. Meanwhile, compared with the prior art, the invention also has the characteristics of high speed, high accuracy, comprehensiveness and the like.

Description

technical field [0001] The invention relates to a frequency domain testing system and method, in particular to a testing system and method for a control network in a flight control system, belonging to the field of testing. Background technique [0002] The flight control system is widely used in computer control, and the design of the control system is usually to complete the design of the continuous system first and then perform discretization processing. a theoretical analysis. [0003] The discretized control system network equations are finally reflected in the flight control software in the form of difference equations. In order to ensure the real-time performance of the control, the flight control software is designed to divide the control network calculation into two parts, the foreground calculation and the background calculation. When a control cycle starts, the guidance law calculation is performed first, then the foreground calculation of the control network is...
