Abstract: An engine control system of a vehicle includes a first temperature module, a second temperature module, and an exhaust gas recirculation (EGR) control module. The first temperature module determines a temperature of gas within an intake manifold of an engine. The second temperature module determines a temperature of an EGR conduit that is coupled to the intake manifold. The EGR control module reduces opening of an EGR valve when the temperature of the gas and the temperature of the conduit is greater than a predetermined temperature.

Abstract: A method, control system, and variable valve timing system are provided for controlling an actuator that can be switched into an on state and an off state with pulse width modulation. The systems and method include controls configured to determine an actual system parameter on a first time schedule and a desired system parameter on a second time schedule. On a third time schedule, a position error difference between the actual system parameter and the desired system parameter is determined. The third time schedule is configured to begin and to determine the position error difference each time that the actual system parameter is determined and each time that the desired system parameter is determined. A desired duty cycle is determined, and a duty cycle command is sent to a pulse width modulation output unit.
