Randy Mackay 67475a9eaa AR_AttitudeControl: reset turn-rate I term if not run for 0.2sec 2018-06-01 15:06:13 +09:00
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 3b71d0360a AR_AttitudeControl: const get_decel_max and get_stopping_distance 2018-05-29 16:37:31 +09:00
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

non-functional change
 2018-05-10 20:37:28 +09:00
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
 2018-05-10 08:02:13 +09:00
Randy Mackay ce44326ba8 AR_AttitudeControl: fix get_steering_out_heading while reversing 2018-05-06 16:58:00 +09:00
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

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
 2018-04-05 12:14:59 +09:00
Randy Mackay d139f0e28e AR_AttitudeControl: add get_stopping_distance 2018-03-14 12:40:04 +09:00
Randy Mackay 5e90cdbf59 AR_AttitudeControl: parameter desc range increase 
new steering controller can use higher FF and zero P

Randy Mackay 1bb18bc941 AR_AttitudeControl: get_throttle_out_speed uses timeout definition 2018-01-05 13:33:21 +09:00
Randy Mackay 4ac5ef3a13 AR_AttitudeControl: allow filter to be zero 
Also increase default filter to 50hz
 2018-01-05 13:33:21 +09:00
Randy Mackay 16d3e5c00d AR_AttitudeControl: add feed foward for speed and steering rate control 2018-01-05 13:33:21 +09:00
Randy Mackay 40bb2b0ad9 AR_AttitudeControl: set throttle speed pid dt 2018-01-05 13:33:21 +09:00

for reporting use only

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.

Randy Mackay b9a1621d38 AR_AttitudeControl: minor comment fix 
non-functional change
 2017-11-27 10:35:26 +09:00

non-functional change

Daniel Widmann 49887235df AR_AttitudeControl: get_steering_out methods accept reverse argument 2017-11-08 14:36:23 +09:00
Randy Mackay ce73d724c8 AR_AttitudeControl: rate-control for skid-steering uses I term even at low speeds 2017-10-26 19:45:04 +09:00
Randy Mackay ee3daaa7c9 AR_AttitudeControl: reset input filter for steering and throttle controllers 
Also only set dt to non-zero value
 2017-10-26 19:44:54 +09:00
Randy Mackay 2986d3eb7d AR_AttitudeControl: fix braking 
this fix ensures the output throttle is never in the opposite direction from the desired-speed
there is a possibility that this could lead to rougher throttle response when the vehicle is transitioning from forward to backwards motion because the throttle response will immediately go to zero when the desired speed cross over zero
