Claim:
1. An engine control system for a vehicle, comprising: a torque requesting module that generates a first torque request for a spark ignition engine based on driver input; a torque conversion module that converts the first torque request into a second torque request; a model predictive control (MPC) module that determines a set of target values based on the second torque request, a model of the engine, and a matrix having dimensions of (m+n) by (m+n), where n is an integer greater than zero that is equal to a number of lower boundary constraints used in the determination of the set of target values and m is an integer greater than zero that is equal to a number of constraints used in the determination of the set of target values other than the lower boundary constraints; a throttle actuator module that controls opening of a throttle valve based on a first one of the target values; a boost actuator module that controls opening of a wastegate of a turbocharger based on a second one of the target values; an exhaust gas recirculation (EGR) actuator module that controls opening of an EGR valve based on a third one of the target values; and a phaser actuator module that controls intake and exhaust valve phasing based on fourth and fifth ones of the target values, respectively.
