How to solve the Hoverboard motor reverse direction move when stop in velocity mode

how to solve the Hoverboard motor(10 pole pair) use build in hall encoder(60 ppr) in velocity mode may have a reverse direction movement when sotp.
https://youtu.be/Xxm1-gWQeik
in this video,the move base reverse move everytime then stop.
I try reduce the vel_gain,but it will cause the motor torque become very low,can anyone give me any suggest about the param adjust,please.or in the low resolution encoder can not have a good control result.

Options:

  1. Set vel_integrator_gain = 0
    or
  2. Use INPUT_MODE_VEL_RAMP (and vel_ramp_rate)

thank you for your suggestion,I try both of the two opthions.
when I set vel_integrator_gain to 0,the motor torque become very low,even can not move the base(no extern load,just like the video show)
and I try set INPUT_MODE_VEL_RAMP and vel_ramp_rate,when vel_ramp_rate is low,the motor Accel very slow ,but if vel_ramp_rate set to the value satisfy my accel,the reverse direction move come back,now this is my controller config below:
gain_scheduling_width = 10.0 (float)
enable_vel_limit = True (bool)
enable_current_mode_vel_limit = True (bool)
enable_gain_scheduling = False (bool)
enable_overspeed_error = True (bool)
control_mode = 2 (int)
input_mode = 2 (int)
pos_gain = 1.0 (float)
vel_gain = 0.15000000596046448 (float)
vel_integrator_gain = 0.5 (float)
vel_limit = 30.0 (float)
vel_limit_tolerance = 1.2000000476837158 (float)
vel_ramp_rate = 8.0 (float)
torque_ramp_rate = 0.009999999776482582 (float)
circular_setpoints = False (bool)
circular_setpoint_range = 1.0 (float)
homing_speed = 0.25 (float)
inertia = 0.0 (float)
axis_to_mirror = 255 (int)
mirror_ratio = 1.0 (float)
load_encoder_axis = 1 (int)
input_filter_bandwidth = 2.0 (float)
anticogging:
index = 0 (int)
pre_calibrated = False (bool)
calib_anticogging = False (bool)
calib_pos_threshold = 1.0 (float)
calib_vel_threshold = 1.0 (float)
cogging_ratio = 1.0 (float)
anticogging_enabled = True (bool)
is ther any other param turn I can try?thank you again!

when I set vel_integrator_gain to 0,the motor torque become very low

Then you need to increase vel_gain

vel_gain increase caused motor shake :rofl:
