Flow model inversion using a multi-dimensional search algorithm

摘要

A system and method for controlling engine coolant including generating one of a plurality of zone flow requests for engine coolant, generating a first search zone, determining a plurality of key points for the first search zone, determining a unique combination of commands for each key point of the plurality of key points in the first search zone, determining a flowrate associated with each command for each key point of the plurality of key points, calculating a total cost for each key point using an absolute normalized error for each flowrate of each command for each key point, determining a first winning key point associated with a lowest total cost, and controlling a plurality of actuators based on the commands associated with the first winning key point.
