A system according to the principles of the present disclosure includes a target turbocharger position module and a turbocharger control module. The target turbocharger position module determines a target position of a turbocharger based on a relationship between power generated by a compressor of the turbocharger, inertia of a shaft in a turbine of the turbocharger, and power generated by the turbine. The target turbocharger position includes at least one of a target vane position and a target wastegate position. The turbocharger control module controls the turbocharger based on the target turbocharger position.

System and method for adaptively learning values and controlling a turbocharger of an engine based on the values

An engine control system comprises a pedal torque determination module, a driver interpretation module, and an actuation module. The pedal torque determination module determines a zero pedal torque based on a desired engine torque at a zero accelerator pedal position and a minimum torque limit for an engine system. The driver interpretation module determines a driver pedal torque based on the zero pedal torque and an accelerator pedal position. The actuation module controls at least one of a throttle area, spark timing, and a fuel command based on the driver pedal torque.
