Flight control distributed type real-time simulation system

Abstract

The invention discloses a flight control distributed type real-time simulation system, relates to the field of flight control simulation, and solves the problems that a model cannot be installed with a large quantity of I / O (Input / Output) physical systems and real-time simulation cannot be realized in the prior art. The flight control distributed type real-time simulation system comprises one or two development host units and multiple target machines, wherein the development main units are system dynamics, navigation and control model development and simulation state monitoring platforms; the target machines are real-time simulation processors; each target machine can be regarded as a node in a real-time network and operates a QNX real-time operating system; the main units are connected with the target machines through a TCP / IP network; the target machines are connected with one another through an IEEE-1394 bus. By the adoption of multi-kernel and multi-model distributed type simulation, parallel simulation of multiple models is realized, and the simulation efficiency is obviously improved; synchronous real-time simulation of the simulation time and the actual physical time is realized; all the models are independent from one another but also cooperated with one another, so that the flexibility of module configuration is improved.

Description

technical field [0001] The invention relates to the field of flight control simulation, in particular to a distributed real-time simulation system for flight control. Background technique [0002] In the field of aerospace, aircraft control systems usually require a large number of simulation experiments and tests in the design stage, through the acquisition of a large number of simulation data, to verify the correctness of the design of the flight control system scheme, and to test the function and performance of the flight control system. [0003] At present, flight control simulation mainly relies on a stand-alone simulation system with only one simulator, which includes a model solving unit and an I / O (Input / Output input / output) interface. The model solving unit is used to realize the numerical calculation of the mathematical model of the physical system, and generally uses a general-purpose computing processing device, such as a central processing unit CPU hardware devi...
