% The longitudinal control laws for an airship.
--------------------------------------------------------------------------
Form:
d = Airship_KLon( action, data )
--------------------------------------------------------------------------
------
Inputs
------
action (:) String name of action to take. Choices are:
* 'init' ... Supply statespace controllers and
initialize matrices
* 'update' ... Supply the error inputs and compute
the controls
* 'reset' ... Reset controller states to zero
data (.) Data structure required for action
if action == 'init'
- data.k_tu ... statespace controller,
u -to- throttle
- data.k_mu ... statespace controller,
u -to- mu (prop pitch angle)
- data.k_dw ... statespace controller,
w -to- elevator deflection
- data.k_dq ... statespace controller,
q -to- elevator deflection
- data.rate ... update rate [Hz]
if action == 'update'
- data.q ... pitch rate error [rad/s]
- data.u ... axial velocity error [m/s]
- data.w ... normal velocity error [m/s]
-------
Outputs
-------
d (.) Data structure of control outputs
- d.throttle ... Throttle command
- d.mu ... Propeller pitch command [rad]
- d.dELV_sym ... Symmetric elevator command [rad]
