1. An engine control system for a vehicle, comprising:

  • 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, respectively;

    determines cost values for the sets of possible target values, respectively;

    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;

    an actuator module that controls an engine actuator based on one of the target values; and

    a fault diagnostic module that selectively diagnoses a fault in the MPC module.
