loop close control system-electronic eye 閉環(huán)控制系統(tǒng)-電子眼
When the user exits the form, the . net framework message loop closes and the earlier application s message loop starts running again 當用戶從窗體退出時,.netframework消息循環(huán)關閉,先前的應用程序的消息循環(huán)再次開始運行。
Here a low cost optimal position system with speed-loop open and position-loop closed based on fuzzy control is presented, it employs fuzzy controller to verdict rotor velocity approximately and a fuzzy switching curve is substituted for real one to achieve bang-bang switch, no limit-loop or oscillation occurs . at the end of this chapter, a dc break curve is discussed 為了實現(xiàn)經(jīng)濟實用的點對點快速定位系統(tǒng),實際系統(tǒng)采用速度開環(huán)、位置閉環(huán)結構,速度量從模糊控制器得到,既不實測也不軟件估計,用模糊開關線代替真實開關線進行控制量狀態(tài)切換,無極限環(huán)或振蕩現(xiàn)象,而成本則大大降低。
