Abstract: A control system for an engine includes an operational data sensor generating signals indicative of operational data of the engine and a controller communicably coupled with the engine and the operational data sensor. The controller operates the engine based on operational parameters defined by a baseline engine model. The controller receives the signals indicative of the operational data of the engine, and generates a dynamic engine model which defines at least one operational parameter of the engine based on the received operational data of the engine. The controller compares the baseline engine model to the dynamic engine model. The controller determines a difference between the baseline engine model and the dynamic engine model based on the comparison. The controller compares the determined difference to a threshold difference value and operates the engine based on the dynamic engine model, if the determined difference exceeds the threshold difference value.
