摘要:
针对 APF( active power filter) 在控制中的混杂特性和饱和非线性问题,提出一种将切换算 法和空间电压矢量控制算法相结合并应用于考虑饱和限幅的三相 APF 的控制策略。该方法首先 建立三相 APF 的切换仿射线性系统的误差模型,根据 Lyapunov 相关定理及凸集理论,为考虑饱和 限幅的三相 APF 找到了一种新的、保守型更小的切换率。然后根据三相电源电压构成的空间电压 矢量图及波形图,三相电源电压被分成六个扇区,再根据凸组合稳定条件,在每个扇区内找到可以 保证系统二次稳定的开关子系统的组合,在这些子系统的组合中选取使得 Lyapunov 函数导数最小 的子系统。最后仿真分析和实验结果证明了所提出方法的可行性和正确性。
Abstract:
Combining switching control with space voltage vector,a method which applies to three-phase APF considering saturation limiting was proposed. First,error model of switching system of three-phase APF was established. A novel conservative stability criterion was found for saturation limiting based on Lyapunov stability theorem and convex set theory. And then according to space vector figure and wave-form,three phase supply voltage was divided into six sectors. Switch subsystem combination which meets quadratic stability requirement was chosen in each sector from convex stability requirement. The subsys-tem which made Lyapunov derivation the minimum was chosen in the subsystem combination which met quadratic stability requirement. Finally,the simulation analysis and experimental results proved the cor-rectness and feasibility of the proposed method.
