Presented in this paper is a robust feedback controller design procedure to regulate the torque of a spark ignition engine equipped with an electronic throttle mass air flow controller. To this end, a system level model of engine torque production is experimentally determined. Next, a crank-angle domain H, controller is designed to control engine torque with zero steady state error while addressing the nonlinear system characteristics and pure delay. The controller design methodology applied to the torque control problem is presented and an interpretation of the controller provided. Engine dynamometer data acquired from a Ford 4.6L V8 engine demonstrates the H controller successfully rejects noise and disturbances while meeting transient and steady state performance objectives.
