Abstract:
A control system includes an error module, a selection module, a control module, and a hysteresis module. The error module determines an error value based on a difference between a desired position and a measured position of one of a throttle valve and an exhaust gas recirculation (EGR) valve of a vehicle. The selection module sets a control value equal to one of the error value and zero based on a comparison of the error value and a hysteresis value. The control module generates a control signal based on the desired position and the control value and actuates the one of the throttle valve and the EGR valve using the control signal. The hysteresis module selectively varies the hysteresis value.
