ABSTRACT:
A system and control method mitigates hysteresis of an adjustable component in the system. A control module can allow small control changes to be effected to the component within limits of the component's and/or the system's normal hysteresis band. The control method can allow finer, more accurate and more aggressive control to be obtained from the component. The system and method can utilize two separate control regimes to control adjustments to the component. The first control regime can control changes larger than a hysteresis band and/or changes in a same direction as the last adjustment that was performed with the first control regime. The first control regime can be a feedback-based adjustment to the component. The second control regime can be utilized to control changes within the hysteresis band. The second control regime can use open-loop based adjustments to the component.
