Active Control of Secondary Current Profile Applied on an Offset Dual-Coil Ignition System

In this article, an active feedback control strategy is introduced to control an offset dual-coil ignition system. By adjusting the offset between the charging durations for the ignition coils, the control strategy can improve the integrity of the secondary current level against the disturbance of external air flow. Experiments are designed to demonstrate the performance improvement of offset dual-coil ignition system after the proposed control strategy has been implemented.
