rmackay9 bdb47c449a ArduCopter: pass linear altitude error to throttle rate controllers. 
Previously the requested rate used the square root of the altitude error.

Scale pilot's desired vertical rate and acceleration based on ACCELERATION_MAX_Z and VELOCITY_MAX_Z #defines
 2012-12-06 10:31:31 +09:00
rmackay9 7b4ed2d227 ArduCopter: restored landing detector to landing throttle mode. 
Added LAND_SPEED parameter to control the rate of descent for the last 10m of a landing.
Added CH6 tuning for accel based throttle controller.
 2012-12-06 10:31:20 +09:00
rmackay9 a94826f182 ArduCopter: add set_throttle_mode to better control initialisation of variables 2012-12-06 10:31:04 +09:00
rmackay9 1036b35128 ArduCopter: added back in angle boost and recombined for heli and multicopter 2012-12-06 10:30:55 +09:00
rmackay9 3cbef57c64 ArduCopter: first merge of leonard's accel based altitude controller plus other changes from Randy 
Changes include:
New low-level get_throttle_accel function takes target acceleration and compares vs earth-frame Z accelerometer values to produce output to motors.
Higher level throttle controllers modified to call new get_throttle_accel controller
Throttle_rate_stabilized controller added which maintains a desired climb/descent rate
Throttle_land controller added - descends using normal auto throttle controller to 10m then descends at 50cm/s
Multiple throttle modes added including landing mode
Land flight mode no longer needs GPS
Throttle cruise maintenance moved to update_throttle_cruise function

rmackay9 a72bf6ef57 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.

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.

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.

Tested in the SIM and in backyard. dramatically increases performance and quad no longer overshoots and flips when pushed hard.

Jason Short 730476fdfd 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
