As an important class of hybrid dynamical systems, a switched system is composed of several continuous time subsystems or discrete time subsystems and the switching signal among them.

切换动态系统是一类重要的混合动态系统，它是由几个连续时间子系统或离散时间子系统及作用在其中的切换规则构成的。

To solve these problems, a modified method is presented, which subdivides the voltage vector sectors and switching signal selection table, and optimized stator flux compensating voltage.

针对上述问题，给出了一种通过细化电压矢量合成扇区和开关信号选择表，优化定子磁链补偿电压的改进方法。

The operating distance is the separation of an object from the active sensor surface at which a switching signal is produced.

经营的距离，是从积极的传感器表面上的一个开关信号分离产生的对象。

Called UMA (Unlicensed Mobile Access), the technology is designed to provide better call quality indoors (where your cell shouldn't otherwise work, natch) by switching over from a weak cell signal to a stronger in-home WiFi signal.
