| Abstract(J) | アクティブエンジンマウント(AEMs)は気筒休止を採用した車の振騒問題を解決できる．通常，AEMsの制御には適応フィルタリングかマップベースのフィードフォワード制御のどちらかを使う．この論文は2つの方法の欠点を補うため両者を組合せた方法を提案している．検証の結果，マップデータ取得時間が節約でき，収束時間も短くなった． Translation |
| Abstract(E) | Active engine mounts make an important contribution to ensure the comfort in vehicles with emission-reducing engine technologies, e.g., cylinder-on-demand (COD). To control active engine mounts either adaptive filtering or map-based feedforward control is commonly employed. This contribution proposes two methods to combine both control strategies in order to overcome their respective disadvantages. Adaptive look-up tables are incorporated into a Multiple-input-multiple-output-Newton/FxLMS adaptive feedforward control algorithm in two ways: as parameter-maps or parallel-maps. The proposed control strategies are experimentally compared in a vehicle with a V8-COD-engine. While both methods significantly reduce the convergence time of the adaptive filter, the parallel implementation additionally improves the tracking behavior during fast engine run-ups. |
