a active constraint

基本解釋

The new manner of active constraint force to control the machinery is broadened the apply of Lagrange equation and break a new thinking for the servo control.
這種在機(jī)械系統(tǒng)中利用主動(dòng)約束力作爲(wèi)控制量的方法拓寬了傳統(tǒng)拉格朗日力學(xué)的應(yīng)用範(fàn)圍，爲(wèi)機(jī)械系統(tǒng)伺服控制理論提供了一個(gè)新的思路。
As a result, the inequality volume constraint is not always active at the optimum solution. In other words, less material may lead to a stiffer structure for an optimum material layout.
