Claim 11:
12. A system for multivariable torque control of a vehicle, the system comprising:
an engine; and
a processor disposed of in a multivariable controller that is coupled to the engine and configured to:
determine a set of references associated with Exhaust Gas Recirculation (EGR);
implement an algorithm based on an engine temperature and at least one reference that is determined of the set of references associated with the EGR to generate one or more commands for the control of a set of actuators;
optimize at least one cam phase position by the control based on a generated command to at least one actuator of the set of actuators to apply an appropriate level of engine torque for vehicle propulsion;
restrict an allowable range of cam phases associated with EGR valve operations for a set of cams based on amounts of humidity and EGR introduced by the EGR valve during an internal combustion phase of vehicle operation; and
provide an amount of propulsion torque by the engine of the vehicle in accordance with instructions provided by the processor.
