微机模糊控制在功率电子学中的应用

Application of Microprocessor Based Fuzzy Control in Power Electronics

针对市用交流电网电压不稳定 ,以致一般的负载很难在其额定电压下工作 ,本文提出了把微机模糊逻辑控制应用于功率电子学领域的交流稳压调压系统 ,通过对晶闸管导通角的模糊控制以达到控制各种负载不同的额定电压的目的。用该方法实现的稳压调压系统为微机模糊控制在功率电子学中的应用提供了一种新的思路。

Because of the instability of alternating current in our lives,the loads can no t work at their rated voltages. This paper proposed a new method which put the microprocessor based fuzzy controller into the alternating voltage′s system of stabilizing and coordinating of the field of power electronics. Aimed at contro lling all kinds of rated voltages of loads, the article used the fuzzy controlle r to control the triggerangle of thyristor. The alternating voltage′s system of stabilizing and coordinating which applied the new method provides a n ew thought to the application of microprocessor based fuzzy controller in power electronics.
