Mostly based on PID and optional reference generators and feedforward gains. An experimental adaptive filter is also included to estimate some parameters, but should not be used for normal operation at the moment.
These initialization functions are called once on startup.

<description>
Adaptive attitude and lateral (heading) control for fixedwing aircraft.
Mostly based on PID and optional reference generators and feedforward gains.
An experimental adaptive filter is also included to estimate some parameters, but should not be used for normal operation at the moment.
