A Hybrid Heterogeneous Simulation Platform for Civil Aircraft Flight Control System

Abstract

The invention provides a civil airplane flight control system mixing heterogeneous simulation platform. The platform employs three flight control module units and four actuator control electronic units for effectively supporting different frameworks in a flight control system 12, 8 actuating strategies of a flight control actuator, and balance and assessment of mixing heterogeneous integration simulation in a flight control system 96; a security analysis in theory is conducted according to the obtained test difference data; and the analysis is stored in an integrated control unit to construct a security analysis database. Each accessed true member and model are synchronized according to heartbeat synchronization. Fault is determined if time isn't synchronized, in this way, fault reproduction and analysis can be conducted; interface analysis and contrast among each accessed true members and the model are conducted according to a general bus management unit and an interface simulation unit; and difference between the model and a true member is improved by improving model simulation degree according to history data and test data.

Description

technical field [0001] The invention belongs to the field of civil aircraft flight control, and in particular relates to a hybrid heterogeneous simulation platform for a civil aircraft flight control system. Background technique [0002] The hybrid heterogeneous simulation platform for civil aircraft flight control system is a simulation test platform for civil aircraft, which is mainly used for the simulation development of flight control system model, the test and verification of the real part access system, and the mixed heterogeneity of the model and the real part joint simulation.

In the common civil aircraft flight control system simulation platforms, there are mainly the Iron Bird platform composed of real parts, or the flight control system model platform based on a single computer for modeling. For the traditional flight control Iron Bird platform, due to the existence of multiple versions The upgrade of flight control software and hardware, the evaluation of configuration differences involved, the analysis of safety impact, the recurrence of system function faults, and the application of multi-system software integration are problems to be solved urgently. For the flight control system model of a single computer, due to the simulation interface It is not clear, the degree of simulation is not high, it has been in the model development stage, and it cannot replace the Iron Bird test bench, and its model replacement function is not outstanding
