ArduCopter: changed all "int" to "int16_t" and a few "long"s to "int32_t".
...
Also moved "simple_counter" variable from global scope to the "update_simple_mode" function which is the only place that it's actually used.

ArduCopter: replaced abs with labs as required in a few places.
...
Also fixed a small bug in the get_stabilize_pitch function in which it was using the roll (instead of pitch) to decide whether it should let the i term build-up or not.

Airspeed patch:
...
pre-calculated airspeed resistance pitches copter automatically to gain a certain speed allowing the speed controller to work off of a better set point - similar to Alt hold.
added param tilt_comp with a default of 54 which equals 19.5° of pitch to go 6m/s
upped Z and Y target speeds to int32_t for speed squared calculation

increased speed governor to get faster WP travel
added param for WP tilt - basically a precalculated I term for wind resistance.

Navigation.pde : removed old cross tracking from Arduplane. Added new 2D cross tracking. Added use of GPS velocity when above 1.5m/s

Inertial Control
...
I added inertial navigation based on the simulator data. This is an option only available if you compile with Arduino and set
#define INERTIAL_NAV ENABLED
in the APM_Config.h file.
This has been tested for one real flight and did not crash my quad, but consider it very alpha. The quad may be unpredictable at first until the error correction fixes poorly calibrated accels. Be Careful.
Most of the real work is in the inertia file, but the error correction, new variable defines and calibration calls are sprinkled throughout.
The Log should record RAW messages with special debugging values.

removed retro loiter code since Angel has a branch now.
...
shrank speed filter to avoid latency
removed unused forward estimator code
placed code for switchover to gps.groundspeed at 1.5m/s
added clamp for D term when below .5m/s to eliminate noise
added hybrid I-term based on speed error and position
changes Loiter D term to use position rather than acceleration to avoid noise

1676e09f12
navigation.pde: Put the new calc_GPS_velocity method in a compiler if that checks the new RETRO_LOITER_MODE config value (saves space and ensures its not being used unless retro loiter mode is enabled)
2012-04-19 10:21:04 -05:00
d29f1ef331
Loiter: Made the "retro loiter" routines configurable. Add RETRO_LOITER_MODE ENABLED to APM_Config.h to enable the older loiter shtuff.
2012-04-19 10:16:29 -05:00
d4a4641ae6

ArduCopter - navigation - corrected comment in check_missed_wp function to clarify that you've passed the waypoint when the direction to the way point is more than 100 degrees off (not 10 degrees off) from your original bearing towards the waypoint

ACM: Broke out the D term for the PID loop to add custom filtering. The current AC_PID filtering wasn't working for this application and we needed more smoothing. Bad pitch oscillations were being transmitted to the copter.
