UPS系统中逆变器的模糊控制技术研究

Study on Fuzzy Control Techniques for Converters in UPS System

研究了UPS系统中逆变器部分的模糊控制技术。针对单相和三相逆变器制定了模糊控制电压外环和PI控制电流内环的双闭环控制策略。并通过Matlab对所设计的系统进行了仿真，仿真结果表明所设计的系统具有动态响应快和稳态精度高等特点。

Fuzzy control techniques for converters in UPS system are investigated. A double closed loop control scheme is set up aiming the single phase and three phase converters, which applies fuzzy control on voltage in the outer loop and PI control on current in the inner loop. Designed system is simulated on MATLAB. Results show that this system owns quick dynamic response and high static precision.
