According as compare of voltage deviation and its variable ratio, optimal control of voltage and current is realized with querying fuzzy control sheet and adjusting adverse variable pulse width.
比较电压偏差及其变化率，查询模糊控制表，调节逆变脉宽，可实现电压及电流的理想控制。

The outer one adopts conventional PI control algorithm and takes the capacitor voltage as the controlled variable.
外环则采用PI控制算法，以电容电压为被控量。

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 feed back.
