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.
Claims21
A method comprising:
- receiving an input signal;
- applying compensation to the input signal to create an output signal, wherein the output signal is configured to be applied to an electronically controlled valve and the valve is configured to use the output signal to control movement of a valve member in the valve, the valve member including at least one land that overlaps an associated at least one opening, and wherein the at least one land is larger than an associated at least one opening such that a dead band is caused, and wherein the compensation is defined to reduce the dead band;
- and
- outputting the output signal.
An apparatus comprising:
- dead band reduction circuitry comprising an input configured to receive an input signal and an output configured to provide an output signal, the dead band circuitry configured to apply compensation to the input signal to create the output signal, wherein the output is configured to be coupled to an electronically controlled valve and the valve is configured to use the output signal to control movement of a valve member in the valve, the valve member including at least one land that overlaps an associated at least one opening, and wherein the at least one land is sized relative to an associated at least one opening such that a dead band is caused, and wherein the compensation is defined to reduce the dead band.
A computer program product comprising program instructions embodied on a tangible computer-readable medium, execution of the program instructions resulting in operations comprising:
- receiving an input signal;
- applying compensation to the input signal to create an output signal, wherein the output signal is configured to be applied to an electronically controlled valve and the valve is configured to use the output signal to control movement of a valve member in the valve, the valve member including at least one land that overlaps an associated at least one opening, and wherein the at least one land is sized relative to an associated at least one opening such that a dead band is caused, and wherein the compensation is defined to reduce the dead band;
- and
- outputting the output signal.
