ABSTRACT:
A digital processor implemented electronic governor for engine-generator units including a first control loop for producing a speed error and controlling fuel delivery setting as a function thereof and a second control loop for detecting rack error and producing a field excitation current control signal as a function thereof. Power dips and overruns are voided by modifying rack error as a function of engine acceleration. Means are provided for developing speed errors and rack control signals despite a breakdown in the rack position indicator. Open loop lower power setting controls are provided. Wheel-slip control, power limiting and variable acceleration functions are provided.
