Randy Mackay cde7d31dad AC_WPNav: fix divide by zero when origin and dest are same location 2014-05-22 21:18:24 +09:00
Randy Mackay 597d5227f5 AC_WPNav: rename set_loiter_target to init_loiter_target 2014-05-19 12:27:25 +09:00
Randy Mackay e7b3c00767 AC_WPNav: set_loiter_target uses set_xy_target
Loiter is only a horizontal position controller so it should not set the
z-axis position.
Moved pos_control.set_speed and accel functions so order matches
init_loiter_targets function order

Ju1ien aed5787c1b AC_WPNav: bug fix for loiter init in Hybrid
AC_PosControl::init_xy_controller() has been added to PosControl and is
called by init_loiter_target.
Hybrid is currently using set_loiter_target function to init the loiter
controller. So we have to call init_xy_controller() by set_loiter_target
function.
What happens otherwise?
In AC_PosControl::update_xy_controller, we update "now" with
now = hal.scheduler->millis();
and, as _last_update_xy_ms has not been updated previously by
init_xy_controller(), we just call init_xy_controller().
So, _dt_xy  will be negative and used anyways in all the functions and
PID called by update_xy_controller.
That will avoid at least _accel_target.x/y to be set to 0 but I'm not
sure for the high values, probably an I_term that is not reset and
reached very high value.
Or maybe a cast error somewhere... no clue at all

Randy Mackay 7dd366d84e AC_WPNav: init_loiter sets speed, accel before calcing stopping distance
The stopping distance depends upon the speed and acceleration so these
must be updated first

Randy Mackay ad99918fee AC_WPNav: recalc leash lengths if set_horizontal_velocity is called
Resolves bug in which do-set-speed allowed reducing the speed during the
mission but not increasing it.
Slow down distance is also recalculated.
Unnecessary call to calc_wp_leash_length removed from
set_spline_origin_and_destination.
