Investigation about Robustness of Air Fuel Ratio Control at Transient State by Fusing Adaptive PID Control and Adaptive Feedforward System

適応PID制御と適応FF機構が融合した過渡時空燃比制御のロバスト性検討

For an improvement of fuel consumption and emission purification, engine operating parameters, such as a valve operation, become variable. Therefore, an engine operation at a transient state was increased and an accuracy was increasingly required to control an air fuel ratio at transient state. This paper investigated an adaptive gain control system which was respectively equipped to the feedforward and the feedback controller. Then, a robustness against operating condition and system parameter were also investigated by comparing with some single side adaptive controller. A high accuracy control result and robustness of the controller were shown by the experimental results.燃費低減と排出ガス浄化のために吸排気バルブ駆動などガソリン機関運転パラメータの可変化が進み、過渡時空燃比制御の高精度化がますます必要である。適応制御を組み合わせることにより高精度でロバストな過渡時空燃比制御ができたことを示す。
