Parameters

  • At high throttle the inner loop causes oscillations with default x quad gains. At low throttle, higher gains give a better response, this suggests that some gain scheduling based on the throttle may improve the overall response and this could be implemented in mc_att_control. For now we will just tune it so that there are no oscillations at low or high throttle, and take the bandwidth hit at low throttle.
    • MC_PITCHRATE_P: 0.05
    • MC_PITCHRATE_D: 0.001
  • The battery has 6 cells instead of the default 3
    • BAT_N_CELLS: 6
