摘要
介绍了多级旋转变压器模糊控制逆变电源。该电源为单输入、多输出高精度电压源。控制器部分采用多赋值模糊式精确控制方式,模糊控制器以输出电压偏差、电流偏差及逆变器导通和关断时间的占空比作为输入量,将输入量进行模糊化处理、判决,得到控制量的精确输出值,从而获得多个等级的标准电压,为多级旋转变压器提供了高精度、多等级电压源。多级旋转变压器可以同时驱动多个被控负载,已达到单输入控制多输出的目的。
The inverted power supply of multipolar resolver＇s fuzzy control was introduced, which is a high- precision voltage source with single-input and multiple-output. The controller adopts a way of multi-assigned and fuzzy accurate control. The inputs of fuzzy controller are output voltage deviation, current-bias,and the dif- ferent dutyfactors of inverter when it is turned on and turned off. These inputs are dealed with in fuzzy process and decided, and finally an accurate output of control variable is available. This helps to get standard voltages of different grades,which provides the multipolar resolver with high precision and multigrade voltage sources. The multipolar resolver can drive more than one controlled loads at the same time,realizing the goal of one single-input controlling multiple-output.
