<p>A motor for driving an exhaust recirculation valve of an exhaust recirculation system undergoes binary control when either the difference between a target value and the actual value or a function defined by the difference and the valve operating speed is large beyond a predetermined range. When the difference or the function is small within the range, on the other hand, the drive motor undergoes PI control. As a result, response and control are stabilized.</p> |
