Abstract(J)本研究では,著者らが構築したモデルに基づくHCCIエンジンの制御器を自動で調整する手法について検討を行った.モデルにはモデル化誤差が必ず存在する一方で,その影響を低減するために導入したフィードバック制御は前のサイクルの情報を用いた制御となる.そのため,過渡条件下では制御性能が悪化することがある.そこで,機械学習によるモデル化誤差の予測に基づいて制御器を自動で調整し,制御性能の向上を目指した.

Translation

Abstract(E)An automatic adjustment method of the model-based controller of an HCCI engine was investigated in this study. As modeling errors are inevitable, the feedback control is usually introduced to reduce the effect of the modeling errors. However, especially under transient conditions, the control performance may deteriorate, because this is a control with the information of the previous cycle. Therefore, we adjusted the feedback input based on the prediction of the modeling error by online machine learning, and the control performance under transient conditions was improved.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
