6. An electronic governor system, comprising:
-
a motor; a transmission coupled to the motor; a throttle plate coupled to the transmission, the throttle plate movable to a plurality of positions between closed and wide-open; an engine speed sensor; and a controller including a feedback control module and an adaptive control module; wherein the feedback control module is configured to; determine an engine speed error based on a comparison of a current engine speed input signal from the engine speed sensor and a desired engine speed; and provide an engine speed output signal to the motor to control the position of the throttle plate to correct the engine speed error, wherein the engine speed output signal is determined by a control algorithm using the engine speed error as an input; wherein the adaptive control module is configured to; determine an expected engine speed error correction based on the engine speed output signal provided by the feedback control module; determine an actual engine speed error correction based on a current engine speed input signal from the engine speed sensor and a previous engine speed input signal from the engine speed sensor; determine a correction error based on the expected engine speed error correction and the actual engine speed correction; and adjust a parameter of the control algorithm of the feedback control module when the correction error is within a predetermined range or outside of a predetermined range. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
