Abstract

The system has a closed-loop control system (14) receiving a reference signal T des related to a desired operating temperature of an engine and a signal T mis related to a measured temperature of the engine. The system (14) generates a component P (cl loop) of a drive signal. An open-loop control system receiving T des generates a component P (op loop) of the drive signal using an inverse engine-radiator thermal system model.
