when the user exits the form, the . net framework message loop closes and the earlier application s message loop starts running again 当用户从窗体退出时,.netframework消息循环关闭,先前的应用程序的消息循环再次开始运行。
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 为了实现经济实用的点对点快速定位系统,实际系统采用速度开环、位置闭环结构,速度量从模糊控制器得到,既不实测也不软件估计,用模糊开关线代替真实开关线进行控制量状态切换,无极限环或振荡现象,而成本则大大降低。
