ABSTRACT:
An apparatus includes dead band reduction circuitry. The dead band reduction circuitry includes an input configured to receive an input signal and an output configured to provide an output signal. The dead band circuitry is configured to apply compensation to the input signal to create the output signal. The output is configured to be coupled to an electronically controlled valve. The valve is configured to use the output signal to control movement of a valve member in the valve. The valve member includes one or more lands that overlaps an associated one or more openings. The one or more lands are sized relative to an associated one or more openings such that a dead band is caused. The compensation is defined to reduce the dead band.
