Control short-term vibration: If the vibration cycle is short is almost the same as the set value of
derivative time (Td), it indicates derivative action is too strong, shorten the derivative time (Td) to
control vibration. When derivative time (Td) is set to 0.00 (namely no derivative control), and there is
no way to control vibration, decrease the proportional gain.
