| 摘 要： | 考虑到有源滤波器数学模型的多变量、强耦合、非线性的特点,提出了基于最小二乘支持向量机(LS-SVM)广义逆系统的三相四桥臂有源滤波器的内模控制策略.利用LS-SVM运算速度快的特点,动态逼近原系统的广义逆模型,同时引入内模控制和解耦控制,构成了广义伪线性复合系统,将控制转化为最优滤波问题.仿真结果表明,该方法稳态精度高,动态响应速度快.

| Abstract: | The dynamic model of the three-phase four-leg active power filter is a multi-variable,nonlinear and strong coupling system.The internal model control based on LS-SVM generalized inverse system method for this system is studied in this paper.The generalized inverse system can be approximated by LS-SVM due to the fast operational speed of LS-SVM.The internal model and decoupling controls are used to construct a generalized pseudo-linear system.In this way,the system control is changed into the Kalman filterin... |
