    Syntax

    addWind(platform,windmodel)

    Description

    addWind(platform,windmodel) adds wind model object to the UAV platform.

    Note

    Simulating a UAV scenario that contains wind models added using the addWind function requires Aerospace Toolbox.

    Create a UAV scenario and platform. Specify a trajectory to fly the platform 5 meters north of the scenario origin at an altitude of 50 meters.

    scene = uavScenario;
platformTrajectory = waypointTrajectory([0 0 -50; 5 0 -50],[0 1]);
platform = uavPlatform("UAV",scene,Trajectory=platformTrajectory);

    Create a steady wind object with default properties.

    steadyWind = uavWindSteady
    steadyWind = 
  uavWindSteady with properties:

     Velocity: [3.5000 3.5000 5]
    StartTime: 0
     StopTime: Inf

    Create a wind gust object with default properties.

    gustWind = uavWindGust
    gustWind = 
  uavWindGust with properties:

    GustAmplitude: [3.5000 3.5000 5]
       GustLength: [120 120 80]
        StartTime: 0
         StopTime: Inf

    Create a turbulence wind object with default properties.

    turbulenceWind = uavWindTurbulence
    turbulenceWind = 
  uavWindTurbulence with properties:

    Add the wind objects to the UAV platform.

    addWind(platform,{steadyWind gustWind turbulenceWind})

    Set up the simulation, and advance the scene.

    setup(scene)
advance(scene);

    Obtain the translational wind velocity on the UAV platform.

    velocityWind = windVelocity(platform)
    velocityWind = 1×3

    3.5753    3.0892    4.5805

    Obtain the angular wind velocity on the UAV platform.

    angularVelocityWind = windAngularRate(platform)
    angularVelocityWind = 1×3
