1. An engine subsystem control system comprising:

  • a mechanism for measuring disturbances variables of automotive control subsystems;

    a model predictive controller that provides model predictive control of the automotive control subsystems to achieve prescribed performance while maintaining controlled variables within prescribed limits based on measurements of the disturbance variables and the controlled variables, the model predictive controller is connected to the mechanism for measuring disturbance variables and is configured to receive values from the mechanism based on the measurements of the disturbance variables; and

    wherein;

    the disturbance variables are uncertain over a prediction horizon;

    the model predictive controller provides estimates of the disturbance variables over the prediction horizon;

    the model predictive controller adjusts a range between limits on the disturbance variables based on the measurements of the disturbance variables-during operation of the automotive control subsystems; and

    the model predictive controller adjusts automotive control subsystem operations to achieve the prescribed performance based on the adjusted range between limits on the disturbance variables.
