Abstract
A control system for a cam phaser can include a cam phaser coupled to a cam shaft, the cam phaser to adjust a position of the cam shaft, an actuator in mechanical communication with the cam phaser, and a controller in electrical communication with the actuator, the controller including a processor and a memory. In one example, the processor is configured to calculate a first hysteresis position of the actuator with respect to a hysteresis band, determine if the actuator is within a first threshold distance of a first edge of the hysteresis band, and if the actuator is not within the first threshold distance of the first edge of the hysteresis band, command the actuator to displace across the hysteresis band.
