A study on automatic adjustment of the HCCI engine controller using machine learning

Nihon Kikai Gakkai ronbunshu, 2022
An automatic adjustment method of the model-based controller of an HCCI engine was designed in this study. As modeling errors are inevitable, feedback control is usually introduced to reduce the effect of the modeling errors.

Adaptive control: Myths and realities [PDF]

, 1984
It was found that all currently existing globally stable adaptive algorithms have three basic properties in common: positive realness of the error equation, square-integrability of the parameter adjustment law and, need for sufficient excitation for ...
