% Gravity turn landing controller.
Thrusts along the velocity vector. You can adjust the forward
and integral games to get a soft landing.
The gravity acts as a bias acceleration.
Type LandingControlGravityTurn for a 2D Europa landing demo.
Since version 2014.1
--------------------------------------------------------------------------
Form:
[u, throttle, d] = LandingControlGravityTurn( v, d )
--------------------------------------------------------------------------
------
Inputs

.tau (1,1) Integrator time constant
.dT (1,1) Time step
.intV (1,1) Integral of velocity
-------
Outputs
-------
