Abstract(J) | モータ電流を入力,バルブ位置を出力とする表記システムの制御系を構築した.各部運動方程式より導出したPID制御には,世代間進化を繰り返す遺伝工学(GA)を応用.シミュレーションの結果,ステップ状のバルブ挙動ではGA準拠の本手法が従来手法より追従性良.また実験との対比で,バルブの目標変化に迅速に追従しており,本手法の妥当性を確認した. Translation |
Abstract(E) | Study on rotary valve system (RVS) for automotive engines has been carried out over many years. Recent researches have already successfully implemented the idea, but none of design can provide variable valve timing and flow area control. Therefore, a RVS with variable valve control system is proposed. The system design and control are presented in the paper. Moreover, the selection of the PID controller parameters for the valve control based on Genetic Algorithms (GA) is also discussed. Experimental and simulation results show that the proposed tuning method is better than the traditional Ziegler and Nichols method, and the proposed RVS is feasible. |
