DOI: 10.1038/s41598-025-27873-2
Abstract: Achieving precise and stable engine speed regulation in spark-ignition (SI) systems remains a challenging task because of the inherent nonlinearities, time-varying characteristics, and external disturbances of internal combustion engines (ICEs). Conventional proportional–integral–derivative (PID) controllers often… read more here.
