CONTROL APPARATUS AND CONTROL METHOD OF ELECTROMAGNETIC DRIVE VALVE OPERATING MECHANISM |
摘要 |
<p>When a target valve timing determined in accordance with the state of operation of an internal combustion engine is acquired, a feed forward control of setting a command timing of a valve body on the basis of the target valve timing and a predicted delay time is performed, and a feedback control of setting the actual delay time in the previous cycle as a predicted delay time for the next cycle is performed. The valve timings (opening, closure) are specified at a timing at which the valve body reaced a position that is apart from a predetermined position on a basis of a buffer height of a buffer mechanism. This makes it to possible to accurately detect the actual delay time in the feedback control, and allows the command timing to be properly set in the feed forward control.</p> |
