摘要
单相H桥整流器的控制面临着动态、稳态性能之间的平衡问题。此处以系统稳定为基础,针对电压环、电流环设计了两个模糊控制器,达到根据工程经验选择参数的目的。通过实验,对比了传统方法比例积分(PI)控制和所设计的模糊PI控制方法的性能,验证了后者具有良好的稳态性能以及快速动态响应的优点。
The equilibrium between dynamic and steady state performance is a main focus of single phase H-bridge rectifier control design.On the basis of principle of system stable,two fuzzy controllers are proposed respectively for current loop and voltage loop,meeting the needing of choose control parameters more reasonable by following expert's experience.Comparing with the proportional integral(PI)control,the experimental results verify that fuzzy PI control has a good performance at both dynamic and steady state.
