% Combined steady-state and gust model for wind. To be used in simulation.
--------------------------------------------------------------------------
Form:
wind = WindModel( action, x, mET )
--------------------------------------------------------------------------
------
Inputs
------
action (:) String argument specifying the action to take
'initialize' Initialize with data. Second input,
x, is data structure with fields:
.jD Initial Julian date at start of sim
.gustPeriod Period at which gust model matrices are updated [sec]
.steadyStatePeriod Period at which steady-state wind is computed [sec]
.sigmaU Standard deviation of gust velocity in x [m/s]
.sigmaV Standard deviation of gust velocity in y [m/s]
.sigmaW Standard deviation of gust velocity in z [m/s]
'xdot' Compute wind gust state derivatives.
Second input, x, is the 5x1 wind gust
state vector.
'update' Update the model and return the
wind velocity. Remaining inputs
for this case described below.
x (.) Aircraft state data structure. The disturbance
state vector must be a 5x1 vector for the wind
gust states: u (1), v (2), w (2).
mET (1,1) Mission-elapsed time [sec]
-------
Outputs
-------
wind (3,1) Velocity of wind in body frame [m/s]
