limited to an engine load the rpm an actual pressure within the intake manifold 106 not shown and or a desired pressure within the intake manifold 106 to be reached by the turbochargers 120 and 122 not shown the desired position determination module 202 determines a desired position of the tbv 138 based on models that relate the desired position to the engine operating conditions for example only a position of the tbv 138 may be in units of percentage and may include a predetermined range of values from u2212 100 e g fully open to 100 e g fully closed the subtraction module 204 receives the desired position and an actual position of the tbv 138 from the solenoid actuator module 140 the subtraction module 204 subtracts the actual position from the desired position to determine a position error the position control module 206 receives the position error and determines a position correction factor based on the position error the position control module 206 uses a proportional integral derivative pid control scheme to determine the position correction factor the force control module 208 receives the desired position and the actual position the force control module 208 determines whether the engine control module 110 is to be set to a force close mode set to a force open mode or reset to a position control mode based on the desired and.
