Randy Mackay 597d5227f5 AC_WPNav: rename set_loiter_target to init_loiter_target 2014-05-19 12:27:25 +09:00
Randy Mackay e7b3c00767 AC_WPNav: set_loiter_target uses set_xy_target 
Loiter is only a horizontal position controller so it should not set the
z-axis position.
Moved pos_control.set_speed and accel functions so order matches
init_loiter_targets function order
 2014-05-19 12:27:20 +09:00
Ju1ien aed5787c1b AC_WPNav: bug fix for loiter init in Hybrid 
AC_PosControl::init_xy_controller() has been added to PosControl and is
called by init_loiter_target.
Hybrid is currently using set_loiter_target function to init the loiter
controller. So we have to call init_xy_controller() by set_loiter_target
function.
What happens otherwise?
In AC_PosControl::update_xy_controller, we update "now" with
now = hal.scheduler->millis();
and, as _last_update_xy_ms has not been updated previously by
init_xy_controller(), we just call init_xy_controller().
So, _dt_xy  will be negative and used anyways in all the functions and
PID called by update_xy_controller.
That will avoid at least _accel_target.x/y to be set to 0 but I'm not
sure for the high values, probably an I_term that is not reset and
reached very high value.
Or maybe a cast error somewhere... no clue at all

priseborough 5fe0d2c1b2 AP_NavEKF: Add protection for accel bias estimation errors 
Don't do bias estimation if tilted by more than 60 degrees to prevent scale
factor errors affecting result unnecessarily.
Prevent Kalman gain from having the wrong sign due to numerical errors
associated with small process noise values.
Allow smaller Z accel bias process noise values to be set

priseborough 3222e8f7cb AP_NavEKF: Default parameter adjustments 
Bring Plane glitch protection thresholds into alignment with copter and
rover
Slight increase in accelerometer bias process noise to prevent bias
estimate divergence into limits (Rover and Plane only as Copter does not
seem respond as well to this change)
effective increase in threshold on divergence test to allow increased
margin for bad GPS velocities

priseborough ce8e1daa16 AP_NavEKF: Improved divergence detection and reset 
Divergence is now detected by looking for very large changes in the gyro
bias. This will cause the filter to be reset and declared unhealthy for
10 seconds.

Don't reset filterDiverged status immediately during reset

Set filterDiverged true if covariance blows up

Add fault status reporting

Andrew Tridgell 85ebe81ed3 AP_NavEKF: fixed logic for divergence test

priseborough 40dc0e56fe AP_NavEKF: Add protection for badly conditioned innovation variances 2014-05-11 18:00:38 +10:00
priseborough 925c5751bd AP_NavEKF: Add ability to inhibit in-flight mag cal and clean up moding 
This will enable in-flight magnetometer calibration to be inhibited unconditionally,
This is required for long balloon carriage flights where ground speed can be high
enough to put it into in-air state, but with very poor observability of magnetic field
states causing bad state estimates and heading offsets to develop over time.

The covariance matrix no longer has rows and columns artificially zeroed when in static
mode. Instead booleans indicating whether wind or magentic field state estimation is
active are used to:

a) Set the process noise on these states to zero to stop their variances from increasing
unchecked when not being updated, and
b) Turn off updates for these states when measurement fusion is being performed.

This reduces the likelihood of a badly conditioned covariance matrix forming
during static mode operation.

A filter divergence check has also been added that will declare the filter unhealthy if
position, velocity and magnetic field observations are all failing their innovation
consistency checks. This unhealthy status will persist for 10 seconds after the
condition clears.

will be used again, but with a reduced weighting.

priseborough d745dc2b6f AP_NavEKF : Increased position gate default to reduce impact of accel errors 
Flight testing with windup turns has shown that the position gate threshold
can be tripped with good GPS data causing position jerks. This increases the
initial GPS glitch rejection threshold to effectively 5m when using the
default POSNE_NOISE value of 0.5m.

priseborough 188bea6bab AP_NavEKF : Enable calc of wind velocity when not using airspeed sensing 
This patch also cleans up the logic associated with use of the synthetic
sideslip measurement so that it can never be used for a non fly-forward
vehicle type

This patch adds functionality that initialises the wind-speed vector to the
reciprocal of the ground speed vector, and scaled to 6 m/s. On average this gives
a better initial wind velocity estimate on launch by assuming:

a) launch will be into wind
b) wind speed is equal to global average

It also helps prevent a headwind causing initial underestimation of airspeed
causing high autopilot gains and limit cycles on climb-out, until first
turn when the EKF is able to estimate the wind.

priseborough aa5335b16e AP_NavEKF : Improved GPS position glitch handling 
When using GPS after previously rejecting it, the GPS position will
always be offset if outside the specified glitch radius. This was the

Aliasing can causes the bias estimate to fluctuate very rapidly as it tries

This patch give a much more stable bias estimate during aliasing, and
allows the bias to adapt at a maximum rate of 1.0 m/s2 in 50 seconds

priseborough 09c5ba1aed Dataflash : Improved logging of EKF sensor health checks 
This changes the definition sof the messages in the EKF4 message to make it more useful
The values shown now relate directly to how much margin there is before a measurement
is rejected, enabling better tuning of error trap parameters

priseborough 04036d7777 AP_NavEKF : Updated GPS glitch protection logic 
This adds new functionality to the detection and compensation of GPS
glitches:

1) A maximum allowable innovation is calculated using the GPS noise
parameter multiplied by the gate, with an additional component allowing
for growth in position uncertainty due to acceleration error since
the last valid measurement
2) Includes per vehicle type values for the acceleration error limit
3) If the innovation length exceeds the maximum allowable, no fusion occurs
4) If no fusion has occurred for long enough such that the position uncertainty
exceeds the maximum set by a per vehicle parameter or a maximum time, an offset
is applied to the GPS data to so that it matches the value predicted by the filter
5) The offset is never allowed to be bigger than 100m
6) The offset is decayed to zero at a rate of 1.0 m/s to allow GPS jumps to
be accommodated gradually
7) The default velocity innovation gate has been tightened up for copter and rover
8) The variance data logging output has been updated to make it more useful
