break curve meaning in Chinese

图示的两个点打断

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。
