Abstract

A base determination module determines a base value based on a base value input. A compensation determination module determines a base compensation value based on a base value input. A compensation coefficient determination module determines a compensation coefficient based on a compensation coefficient input. A multiplier module determines a compensation value based on a product of the base compensation value and the compensation coefficient. A target module determines a target value based on the base value and the compensation value and controls an actuator based on the target value. A calibration module selectively displays predetermined options for calibrating one of the base compensation value input and the compensation coefficient input and sets the one of the base compensation value input and the compensation coefficient input to a selected one of the predetermined options.
