A high-efficiency simulation verification method for launch vehicle flight quality

Abstract

The invention discloses a carrier rocket flight quality high efficiency simulation verification method. The carrier rocket flight quality high efficiency simulation verification method comprises steps of designing a static state test, an open loop test and a closed loop test to carry out checking, verification and confirmation on a carrier rocket body model, adopting a standard script file to compile a deviation parameter of a guiding system and a deviation parameter of a attitude control system into multiple instance cases to realize a fact that various deviations are injected into a simplified mathematic model, connecting an airborne computer and a ground simulation system to form a closed loop, respectively operating flight control software and carrier rocket body model simulation software, performing a traverse test on the test case to determine a boundary test case, connecting main test units to form a closed loop to carry out a hardware in-loop simulation experiment. The carrier rocket flight quality high efficiency simulation verification method realizes synchronous checking on various indexes of the guiding system and the attitude control system is on a same platform through designing the guiding and altitude control synchronous simulation checking technology, saves simulation test resources, saves human resources and guarantees updating consistency between the simulation model and a software edition.

Description

technical field [0001] The invention relates to a simulation verification and testing method of a launch vehicle control system. Background technique [0002] In the traditional development process of the launch vehicle control system, the guidance system and the attitude control system have different evaluation indicators, so two sets of simulation systems need to be developed for the closed-circuit guidance simulation test and the six-degree-of-freedom attitude control simulation test. In the traditional simulation test mode, two sets of test personnel and two sets of simulation software are required, which has problems such as high test resource cost, high labor cost, long test period, and inconsistent software version updates. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] Aiming at the above-mentioned technical problems in the related art, the present invention proposes an e...
