Roman 55401ec1b0 fw attitude control: compute integrator correctly 
- I gain was applied wrongly, such that the integrator value was depending
direcly on the I gain. This made the integrator value jump when the gain
was changed

Roman ac7fc30ea7 fw attitude controllers: restructuring in order to allow acro flight mode 
- split rate control into body rate control and euler rate control
- this allows standard attitude control but also direct rate control
of all three axes
- allow activation/deactivation of turn compensation

Paul Riseborough a776b2c549 EKF: Fix bug preventing reset to GPS position when using optical flow 2016-11-26 10:28:58 +01:00
Paul Riseborough 460c9e5250 EKF: Don't try to fuse air data if not in normal aiding mode 
Taking off before passing GPS checks would cause airspeed or sideslip to be fused when the filter was still using a constant position assumption. This would cause large airspeed innovations, invalid wind estimates and degrade filter performance after GPS was gained and position and velocity was reset.

Paul Riseborough 750a8874c1 EKF: Improve recovery and reporting for badly conditioned sideslip fusion 
Do not reset the entire covariance matrix if we are only using sideslip fusion to update wind states.

Paul Riseborough f76a2a5ff7 EKF: fix bug in sideslip fusion and reduce RAM usage 
The bug meant the  Y velocity (state index 5)  covariance was not being updated correctly when sideslip was being used to constrain velocity drift (extended GPS loss).
The rework of the covariance update to reduce RAM follows the same pattern as adopted for other fusion processes

Paul Riseborough 951c8b77af EKF: Improve wind state reset logic 
Enables wind estimation without an airspeed sensor and enables synthetic sideslip to be used with an airspeed sensor for improved wind state estimation.
Wind states and covariances are reset differently depending on whether airspeed is available.
