Decoupling control of active power filter based on neural network inverse
摘要
Abstract
Three-phase shunt active power filter is a multiple-input multiple-output nonlinear system, in which a coupling relationship exists between the compensation current components under the synchronous orthogonal d-q frame. A new decoupling control method for active power filter by employing neural network inverse is proposed. By adopting the static neural network inverse control method, the three-phase shunt active power filter is decoupled into two one-order linear subsystems, which concern the compensation current components. Then, the linear closed-loop controllers are designed to control the compensation current components respectively. Simulation results verify that by applying the proposed control method, the system has both good steady-state and dynamic performances. After the compensation, the total harmonic distortion of the power source currents in steady state is less than 2%.关键词
