ABSTRACT:
In a fuel injection system for an internal combustion engine having a positionable valve which controls an amount of injected fuel during a cycle of the internal combustion engine in response to a control signal, a system for controlling the valve position includes an error signal generator for generating an error signal based on the difference between the desired valve position and the actual valve position. A feedback controller generates the control signal based on a fourth derivative, with respect to time, of the error signal.
