This paper applies a method of linear continuous variable feedback to the control of a kind of voltage collapses induced by reactive power changes, which only USES a single variable to feedback.
应用连续变量线性反馈对一类由负荷无功功率变化引起的电压崩溃进行控制，仅用单个变量即可实现。

A impedor is connected between the input and the load. The impedor is automatically adjusted by linking feedback loop for the purpose of stabilizing the output voltage.
