Jason Short 0ccf5724aa Small fix to angle boost - increases by about 20% to deal with inefficiencies of non-downward thrust 2012-06-20 08:47:47 -07:00
Jason Short 6dc1e02f76 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.

rmackay9 3618ac62e0 ArduCopter: made Robert's new yaw method optional (off by default).
Add this line to APM_Config.h to enable Robert's yaw
#define ALTERNATIVE_YAW_MODE ENABLED

Robert Lefebvre 1b789b7928 Yaw Fix
Modified Nav_Yaw controller to better track intended heading changes.

Jason Short 71111a5816 Stabilization patches
removed Angle error limit for stabilization
constricted Iterm to +- 5° error and limited the implementation to when the quad is +- 5° from center
doubled the output limit for Rate controller.
increased default Rate_P gain to .18 with matching Rate_D of .004
Tested in the SIM and in backyard. dramatically increases performance and quad no longer overshoots and flips when pushed hard.

Jason Short 6c999b5d54 Attitude.pde - Removed rate limit based on SIM flights. These should never have been in place and seriously detriment Acro flight. 2012-05-21 09:58:23 -07:00

rmackay9 23c3f25654 ArduCopter - Attitude.pde - moved heli_get_angle_boost from heli.pde (which will be removed) to Attitude.pde. In fact we should combine heli_get_angle_boost and the regular get_angle_boost. 2012-04-04 22:51:39 +09:00

Jason Short 285f2dd791 ACM: removed the experiment for rate error. 2012-03-10 12:38:29 -08:00
Jason Short 43b3e1ccd1 ACM -
Implemented automatic ranging of Alt Hold gains. Works well in simulator and testing.
- alt hold estimation moved to 50 hz
- simple fixed observer calc for smooth and accurate climb rates useful for derivative calcs
- auto-reset of the I term by moving I value into throttle value. This recalcs the gain every 20seconds for battery drainage compensation in long flights.
- remove filtering for Nav_throttle
- added a way to lower the gain on nav_throttle for descents by / climb_rate error by 2 - seems to work OK and keeps copter from dropping like a rock when the Baro drifts quickly lower.
- removed old throttle hold set point code
- made throttle override for alt hold +- 200 vs 250
