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
2018-05-29 16:37:31 +09:00
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
2018-05-24 11:06:20 +09:00
Randy Mackay c032095c80 AR_AttitudeControl: reduce default accel max to 2m/s/s 2018-05-24 11:06:20 +09:00

Ammarf a9ee949c32 AR_AttitudeControl: limit desired steering rate 2018-05-21 09:48:43 +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 0f9b679e98 AR_AttitudeControl: increase angle err P and reduce steering accel max defaults 2018-04-26 14:16:22 +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 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

Randy Mackay 23ed735304 AR_AttitudeControl: reduce default steering I gain to 0.2
Also reduce default filter from 50hz to 10hz
2018-04-19 16:29:12 +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

Randy Mackay 57f2eb6853 AR_AttitudeControl: minor comment fix 2018-03-31 14:47:30 +09:00
Randy Mackay 89725a7aa5 AR_AttitudeControl: minor comment fix
non-functional change
2018-03-15 09:58:27 +09:00
Randy Mackay d139f0e28e AR_AttitudeControl: add get_stopping_distance 2018-03-14 12:40:04 +09:00
Randy Mackay 54d8a4852f AR_AttitudeControl: reduce steer rate P default to 0.2 2018-03-09 13:17:38 +09:00
Randy Mackay 2aeda48512 AR_AttitudeControl: minor arg name fix
non-functional change
2018-02-09 17:36:21 +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 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
2018-01-05 13:33:21 +09:00
Randy Mackay f00f4ce79b AR_AttitudeControl: fix get_desired_speed timeout 2017-12-09 16:23:22 +09:00
Randy Mackay 36c5f057ae AR_AttitudeControl: add get_desired_turn_rate lat_accel and speed
for reporting use only

khancyr e9e1dac188 AR_AttitudeControl: remove unused skid_steering arg from get_throttle_out 2017-11-08 15:45:35 +09:00
khancyr aa09541847 AR_AttitudeControl: const ahrs reference 2017-11-08 15:34:41 +09:00
khancyr d226ffeeb2 AP_AttitudeControl: remove tabs
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 9f876dc7a0 AR_AttitudeControl: throttle and steering control library
Throttle controller has these advantages over existing controller:
based on velocity in vehicle's forward-back axis rather than ground-speed
straight-forward PID controller using speed error as input
speed control acceleration limts
stop control slows vehicle smoothly
configurable filtering

Steer controller has these advantages over existing controller:
output scaled properly for skid-steering vehicles
layered P and PID controller for angular error and rate control
configurable filtering
