Randy Mackay 67475a9eaa AR_AttitudeControl: reset turn-rate I term if not run for 0.2sec 2018-06-01 15:06:13 +09:00
disgruntled-patzer 2c41db9e4d AP_RollController.cpp: Updated description of ArduPlane Roll Controller for accuracy 
AP_RollController's get_servo_out function does not return an elevator deflection as was previously described in the function comments.
Instead, it should return an aileron deflection. Thus, the function description should be updated to reflect this more accurately

Randy Mackay e691b680ca AR_AttitudeControl: add speed-control-active method 
allows caller check if speed controller if active
also consolidated other methods to use this check to reduce a little bit of duplicate code

Randy Mackay a7fbfe7767 AR_AttitudeControl: caller provides dt instead of calculated internally 
This allows the vehicle's main loop rate to be used instead of an internally calculated dt which suffers from jitter

Randy Mackay fa76a7c904 AR_AttitudeControl: get-steering-out-lat-accel uses negative speeds 2018-05-10 08:02:13 +09:00
Randy Mackay 5563691bd1 AR_AttitudeControl: assume positive steering output rotates vehicle clockwise 
also remove steering scaling by speed which has been moved to AR_MotorsUGV

Randy Mackay 3f1f68b130 AR_AttitudeControl: support vectored thrust 
steering output is not scaled for speed
steering integrator does not build up at low speed
 2018-04-24 19:57:19 +09:00
Randy Mackay 9c2da896b9 AR_AttitudeControl: get_throttle_out_stop only stops once desired speed reaches zero 
this reduces the final jerk to a when transitioning from forward to reverse and in cases where ATC_ACCEL_MAX is small
 2018-04-24 12:24:53 +09:00
Randy Mackay 365e1030db AR_AttitudeControl: separate speed limiting to new method 
This allows the desired speed limiting (by acceleration) to be done before the speed-to-throttle PID controller is run.
This is required so the avoidance calls (which work on the desired speed) can be run after limiting but before the PID controllers
 2018-04-24 12:24:53 +09:00
Randy Mackay 23ed735304 AR_AttitudeControl: reduce default steering I gain to 0.2 
Also reduce default filter from 50hz to 10hz

Daniel Widmann 27234f78c6 AR_AttitudeControl: Allow using steer rate control for skid steer rovers without GPS 2018-04-13 09:12:03 +09:00
Randy Mackay a8857726d1 AR_AttitudeControl: replace get_steering_out_angle_error with heading 
internally uses AHRS's heading to determine angle error so overally a non-functional change
 2018-04-05 12:14:59 +09:00
Randy Mackay e6f8021519 AR_AttitudeControl: add angular accel and rate limits 
This limits the change in desired turn rate to reduce impossible requests which should help avoid overshoot
Also add rotation rate limit to turn-rate controller

new steering controller can use higher FF and zero P

Randy Mackay 4ac5ef3a13 AR_AttitudeControl: allow filter to be zero 
Also increase default filter to 50hz

Randy Mackay 9930550cfc AR_AttitudeControl: lengthen timeout to 200ms 
This is required because occasionally the turn rate controller can be disabled for just over 100ms as new navigation commands are loaded

Andrew Tridgell 1dac512567 APM_Control: removed create() method for objects 
See discussion here:

  https://github.com/ArduPilot/ardupilot/issues/7331

we were getting some uninitialised variables. While it only showed up in
AP_SbusOut, it means we can't be sure it won't happen on other objects,
so safest to remove the approach

Thanks to assistance from Lucas, Peter and Francisco

Grant Morphett f7db538220 APM_Control: Fixed the subparam indexs to start at 1 
AFAIK there is still a bug in ArduPilot where subparams should not start at index 0.  This is due to the way the index math and bit shifing works as it incorrectly offsets all 0 index params to 0. We allow 2 levels of sub params - 3 levels in total.  So params, sub params and sub sub params.  The 0 parameter in all those is unfortunately always references param[0].  So param[0] and subparam[0] and subsubparam[0] will reference the same parameter value.  Its why we always say start the index from 1 as the math and bitshifting then works correctly.

Yeah this is worded badly - hard to explain.
