Abstract(J)パワートレインでは,加速時に発生する低周波振動の低減が要求される.モデルベース制御系はシステムのモデルに依存するため,実制御対象のパラメータ変動により制御性能が低下し得る.本研究ではパラメータ変動を考慮した深層強化学習により制御方策を獲得し,変動下における制振性能/ロバスト性能を向上させる.

Translation

Abstract(E)In automotive powertrain systems, reducing low-frequency vibration during acceleration remains a challenging issue. Since model-based control systems depend on system models, their control performance may degrade due to parameter variations in actual plants. This study obtains a control policy using deep reinforcement learning that accounts for parameter variations, thereby improving vibration suppression and robust performance under varying conditions.

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.
