中文摘要	For the control of shunt APF(active power filter), feedforward is an effective way to track the load variation, but accurate models and parameters are demanded. To eliminate the influence of errors between realistic and ideal control instructions on the compensation effectiveness of APF, a state-space model of distribution system with APF containing a HPF(high-pass filter) is established. Taking errors as unknown disturbances to the system, a supplementary feedback controller based on the H/sub infinity / control theory is designed. With a given interference suppression ratio, corresponding feedback parameters can be obtained by solving the Riccati equation. When positive definite solution exists, the smaller the interference suppression ratio is, the stronger interference suppression capability the close-loop system will have. The controller ensures the stability of the close-loop system with effective compensation. Simulation results prove that, the APF with the designed controller performs well for both stable load and sudden-changing load.
