8ca99739ed Changed rate controller from PID to PIDT1 to improve flight stability. 
Low pass on D-Term makes the D-Term usable to improve flight stability.
Affects rate and stabilize mode.

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.

4afd9d110e Don't zero the PIDs when the settings are updated. Fixes some quirks from

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

59972d5570 Limit the number of degrees the vbar can deflect. This is good for fast flips 
etc.

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.

feedback.

fe978504bc Add friendly settings for the vbar mode including the VbarTau which acts like

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

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.

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.
