| Abstract: |
| With the fast development of power electronics and control theories,the modern control theories are applied into the APF(Active Power Filter)farther and wider.The recent researching achievement is overviewed to help the engineer grasp the status and the future in this field.The principles and characters of APFs are stated.The applications of modern control theories in APF,such as adaptive control,sliding mode control,feedback linearization de-coupling control,passivity based control and intelligent control,are discussed in detail.Every control strategies have their own merits and demerits.For the disadvantages of the current researches,the control methods that is more robust and with little dependence on the model of the system are better to solve the uncertainty and stability of the APFs.They are sliding mode control,robust control,passivity based control and intelligent control and so forth.This project is supported by Guangdong Key Scientific Fund(A1050202)and National Key Re-search Fund(1998020308). |
