Abstract: A method of controlling an HCCI engine-based power system may include receiving performance information relating to a desired operating state for the HCCI engine-based power system, evaluating operational information associated with a current operating state of the HCCI engine-based power system, and determining one or more control parameter values based on the performance information and the operational information. The method may further include predicting a response of the HCCI engine-based power system based on the one or more control parameter values and determining whether the response satisfies one or more desired performance characteristics associated with the HCCI engine-based power system. If the response satisfies the one or more desired performance characteristics, control of at least one component of the HCCI engine-based power system may be enabled based on the one or more control parameter values.
