Hardware-in-the-Loop Simulation - An Engine Controller Implementation

This paper describes a real-time engine simulation with an engine controller in the loop. The extremely high update rates needed to interface to the controller and the many types of signals required by the controller place great demands on the interface between the engine control unit and the digital simulation of the engine. The interface used to meet these demands is a distributed processor simulation system, the Applied Dynamics Real-Time Station. The interface system and the method used to schedule the processors to execute the engine hardware-in-the-loop simulation are described in this paper.
