addWind

Add wind model object to UAV platform

Since R2024a

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.

Examples

Generate Wind in UAV Scenario

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

   -0.0484   -0.0323   -0.0419

Input Arguments
