| 摘 要： | 有源电力滤波器是一个非线性、多变量、强耦合的系统，建立精确的数学模型比较困难。文中在其非线性数学模型的基础上，采用非线性变换和非线性反馈理论，推导出其反馈线性化方程，从而得出有源电力滤波器有功电流和无功电流的解耦控制策略。数字仿真和实验结果表明，该控制策略能较好地实现有源电力滤波器的解耦控制，具有较好的动态特性和较强的鲁棒性。

| Abstract: | An active power filter is a nonlinear multivariable system with strong coupling. It is quite difficult to modify the power filter by use of the precise model. This paper adopts theory of the nonlinear transformation and nonlinear feedback, creates the nonlinear model of the power filter, and deduces its feedback linearization equation. Consequently, the active and reactive current decoupling control strategy is proposed. Simulation and experimental results confirm the decoupling control strategy for the power filter. It has preferable dynamic characteristics and robust quality. |

| Keywords: | active power filter nonlinear system decoupling control feedback linearization robustness control |
