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.

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.
