Use of predicted RPM in multi-variable engine control with least-square techniques

摘要

An engine control system for a vehicle, includes a model predictive control (MPC) module that identifies sets of possible target values based on an engine torque request, determines predicted operating parameters for the sets of possible target values, determines cost values for the sets of possible target values, selects one of the sets of possible target values based on the cost values; and sets target values based on the possible target values of the selected one of the sets; and a first actuator module that controls a first engine actuator based on a first one of the target values. The MPC module determines at least one of the predicted operating parameters at a future point in time based on a predicted value of engine rpm, which is determined based on a plurality of recent engine rpm measurements.
