Abstract
A system for controlling operation of engine fuel injectors that includes a feed-forward control unit responsive to signals from sensors on the engine for supplying a basic electronic control signal for the injectors. A neural network is connected in parallel with the feed-forward control unit for receiving the sensor signals and multiplying the sensor signals by associated weighting factors. The sensor signals multiplied by the weighting factors are combined to produce a network output signal, which in turn is combined with the basic control signal from the feed-forward control unit to control operation of the fuel injectors. The weighting factors in the neural network are modified as a function of inputs from the engine sensors so as to reduce any errors in the sensor output signals as compared with desired values.
