example

[0071] First, in terms of initial settings: the initial heading is 0 (true north);

[0072] After starting the real-time code and establishing the communication between the host machine and the target machine, it is necessary to convert the Simulink model into real-time embedded code and download it to the xPC target machine. At this time, it is necessary to configure the simulation parameters and the RTW generated file type. When setting the simulation parameters and the RTW generated file type, select the Real-Time Workshop / Target Selection dialog box in the model window menu, set the System target file to xpctarget.tlc, and set the languages ​​to C.

[0073] In terms of RTW parameter setting: only a few parameters need to be modified during testing:

[0074] (1) Solver (solver) uses ode4Runge-Kutta (fourth-order Runge-Kutta method). The calculation error of the fourth-order Runge-Kutta method is small, and it can realize self-starting. When the model is not very complicate...

Abstract

The invention relates to a method and a system for a semi-physical simulation test of visual unmanned aerial vehicle flight control and belongs to the technical field of visual system simulation. The method includes building a dynamic model of an unmanned aerial vehicle system, initializing the dynamic model, enabling an unmanned aerial vehicle to fly along the track provided by the ground, feeding flight rudder quantity information to the dynamic model to be updated, driving a three-dimensional model of the unmanned aerial vehicle through the updated dynamic model to conduct simulation and outputting simulation image and data in real time. A system based on the method is further provided. The method and the system provide effective ways and development environment for design, experiments and verification of the flight control law, have the advantages of being simple, flexible, quick, vivid and real-time, improve simulation efficiency of a flight control system, reduce test risk and test cost of the unmanned aerial vehicle and shorten development period.

Description

technical field [0001] The invention relates to a visual UAV flight control semi-physical simulation test method and system, belonging to the technical field of visualization system simulation. Background technique [0002] Semi-physical simulation refers to the simulation of connecting some physical objects such as controllers, actuators or sensors in the simulation loop of the system. For the relatively simple part of the system or the part whose laws are relatively clear, or the part that cannot be connected to the system due to conditions, a mathematical model can be established on the computer to realize it, and for the more complex part that can be connected to the system , can use physical objects for simulation, which can avoid the problem of difficult modeling of some parts. [0003] However, this hardware-in-the-loop simulation technology can only provide numerical calculation data, and lacks the visibility, vividness and intuitiveness of the simulation object, si...
