The current and speed PI regulator parameters are designed using the lefthalfplane zero-pole cancellation method.
采用左半平面零极点相消的方法设计了电流及转速PI调节器的参数;

The value function turns out to be continuous in the whole plane, and is even continuously differentiable in the interiors of both right and lefthalf planes.
说明了值函数在整个平面上是连续的,在左右两个半平面的内部还是连续可微的。

A spokesman said the plane was checked, no bomb was found and the aircraft left an hour and a half late. He added that such alerts were relatively common.
