A Novel Approach to Engine Torque Speed Control

THIS PAPER DESCRIBES A NOVEL APPROACH to the design of an engine torque/speed controller. Since all the information necessary to design the controller is obtained directly from a small number of step response tests, the necessity of first producing a control model for the engine is avoided, thus effecting, considerable savings in time and effort. Further, although the independent control of an engine's torque and speed is not trivial, the resulting controller has a simple physical structure which makes the device easy to manufacture and inexpensive. The method of control and the required design stages are all demonstrated using a Ford 1.1 L CVH engine.
