Peter Dürr 5988900044 Add getters for a few private variables of the EstimatorInterface 
* For testing it is useful to have access to more internal states
* For the same reason I also promote the const FILTER_UPDATE_PERIOD_MS to
  public
 2017-08-14 12:02:03 +02:00
Peter Dürr a2ed0a76f9 Make the destructor of EstimatorInterface virtual 
* This is a sane choice (and should arguably always be done for classes with
  virtual methods to avoid undefined behavior)
* It is required for wrapping the EstimatorInterface with SWIG (without virtual
  destructor, deriving from the EstimatorInterface leads to
  -Werror=delete-non-virtual-dtor).

Paul Riseborough fed4a9bc5a EKF: add vertical position derivative output 
Add calculation of a vertical position derivative to the output predictor. This will have degraded tracking relative to the EKF states, but the velocity will be closer to the first derivative of the position and reduce the effect inertial prediction errors on control loops that are operating in a pure velocity feedback mode.
Move calculation of IMU offset angular rate correction out of velocity accessor and into output predictor.
Provide separate accessor for vertical position derivative.

Paul Riseborough 5fb24c3032 EKF: Reduce EKF prediction delta time jitter 
Make the target EKF rate an integer multiple of the IMU rate. This slightly increases the average prediction time step for the EKF from just over 10msec to 12msec, but the variation reduces significantly which makes filter tuning more deterministic.
Improve the algorithm used to adjust the collection time criteria to reduce jitter in the correction.
