Method and apparatus for controlling motor drive type throttle valve |
摘要 |
When the position of a throttle valve approaches a target value, an integration calculation of position control is stopped. When a deviation from the target value increases, the integration calculation is restarted. If an integration value includes no frictional amount, a motor output in which a motor and a spring are matched is set synchronously with a change in target value.
