Jason Short 2df487ab7b Arducopter: Slower WP deceleration for RTL and WP navigation
Slower descent and slightly faster ascent
2012-07-19 09:50:18 -07:00
Jason Short c995749aaa Arducopter
upped nav max to 32deg from 30
renamed calc_desired_speed to get_desired_speed
Added get_desired_climb_rate function to do smooth transitions in altitude
modified get_altitude_error to override the older altitude manager.

Jason Short 038116f521 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
2012-07-09 13:13:32 -07:00

Jason Short c29a0bc3f8 Navigation
increased speed governor to get faster WP travel
added param for WP tilt - basically a precalculated I term for wind resistance.
2012-07-03 17:34:50 -07:00
Jason Short 1a6549fef7 removed GPS ground speed calc - was causing some funny business during the transition. 2012-07-03 17:16:14 -07:00
Jason Short eea788b63f navigation.pde : Added a drag/velocity prediction filter for improved I term wind correction. 2012-06-29 21:20:28 -07:00
Jason Short 53d2a46cd6 Navigation.pde : removed old cross tracking from Arduplane. Added new 2D cross tracking. Added use of GPS velocity when above 1.5m/s 2012-06-25 23:06:28 -07:00
Jason Short c42f9ece43 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.

2012-05-15 22:14:23 -07:00
Adam M Rivera b2a7227ae7 ArduCopter/Navigation: Updated code to reference the new g.retro_loiter param instead of the compile define. 2012-04-23 00:19:18 -05:00
Adam M Rivera 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
Adam M Rivera 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

Jason Short deed802d1a 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. 2012-03-11 23:21:49 -07:00
