rmackay9 485cebf85c ArduCopter - bug fix to calc_XY_velocity (was using uninitialised last_longitutde and last_latitude for speed calculations) 2012-03-18 12:11:12 +09:00
Jason Short f6638d00d6 ACM: Smoother Speed calcs 2012-03-16 14:10:19 -07:00

Jason Short 580c5e109e ACM: Got the sign wrong. I'm using the derivative of the error now and not the sensor, so the sign was reversed. 2012-03-12 13:11:05 -07:00
Jason Short 56d2b9ef05 ACM: Broke out the D term for the PID loop to add custom filtering. The current AC_PID filtering wasn't working for this application and we needed more smoothing. Bad pitch oscillations were being transmitted to the copter. 2012-03-11 23:21:49 -07:00
