Use of Transient Data to Derive Steady State Calibrations for Dynamic Systems

Abstract: 

A method of identifying target outputs, such as emissions levels, for a dynamic system, such as an engine. The engine is run at numerous combinations of input parameters, such as actual settings. At each combination of input parameters, the system is driven to a "quasi-steady" state, rather than waiting for it to reach a steady state. Response data collected at this quasi-steady state is used as the basis for identifying the target outputs and the associated inputs.
