tool.

561cf994b0 Reduce the memory footprint of the sin lookup table by using sin(x+pi) = 
-sin(x).  Still just needs to move into flash and have some options about
precision when in its own library function.

17878b32f3 Make autotune run within an attitude loop instead of direct rate mode. Easier 
for beginners.

44e72d0a70 A big refactoring of stabilization.c to get rid of the two separate loops and 
move them into one big structure.  This makes it easier to implement other
modes.

46a52fc5ce Apply the virtual flybar stick scaling in stabilization.c because we need to 
know the true stick position to dampen the gyros appropriately.

42ac4018b8 Woops. Fix really nasty bug in vbar mode I introduced. Also fix small bug in 
scoping of gyro gain that made it not work.

ff1b1a93cf Implement a virtual flybar in a way inspired by behavior of Align 3G which 
seems apply a leaky integrator to the swash angle.  This is the similar to what
is done by Phubar (http://code.google.com/p/phubar/) as well although we refer
to the gyro term as the proportional and the flybar angle as the integral

b38081bb1b Stabilization: When in none mode zero the integral accumulators for rate and 
attitude loops.  When not using outer loop zero that accumulator.

482bec497b Revert "Fixed modules that didn't initialize used UAVObjects correctly" 
Modules should initialize their settings and the objects they source.  Not just
everything.

This reverts commit 9ad85e9b7b.

ab288e95ab Stabilization: Small patch so that by default the integral is zeroed while 
throttle is low (good for quads) but can be disabled (good for planes and also
testing helis).

612a439199 OP-423: simplify the MODULE_INITCALL macro and remove the ordering loops 2011-07-12 20:44:32 -07:00
James Cotton
0aec3b592c Changing stabilization so that the PIDs are zeroed when not armed, but NOT when 
the throttle is < 0.  This will make things like axis-lock work while armed
without throttle.  HOWEVER don't hold your stick in the arming position for a
long time or you can wind up the integrals now.

a7206361d2 Slightly different way to respond to sticks in axis lock that is much more 
responsive and avoids overshoot.

28501842c3 Expose the rate D term which in simulations seems to help damp oscillations for 
high RateKp terms.  However it might be sensitive to gyro noise (vibrations).
In addition it is mathematically similar to lead shapign so probably only use
one or the other.

a09642675c Tweak the integral calculation so it is scaled in ms internally. This avoids a 
loss of precision on the accumulation.

373689207a Add a 1-tap IIR filter into the gyros in the feedback path. This will make the 
stabilization output a bit more resilient to the high frequency noise from
gyros.  However this value shouldn't be too high as it will increase the phase
delay of the feedback loop and decrease stability.  Default is 5 ms.

Note: this resests the stabilizationsettings object.  Sorry guys.
