Study on Nonlinear Problem of Active Noise Control System for Power Transformers

Abstract:

With the development of active noise control technology, ANC system has been gradually introduced into practical application. And some researches and experiments notice that ANC system may encounter with nonlinearity problems under certain conditions in practical applications. The paper analyses and summarizes possible factors that may lead to nonlinearity problems, based on the operation principle and structure features of ANC system, and classifies the main methodologies of dealing with nonlinearity problems considering the main technologies and researches nowadays of system nonlinearity with the same analyzing structure of nonlinearity factors mentioned in the paper. The paper also elaborates the strength and weakness of different methodologies and the most appropriate application condition for each methodology, and it provides theoretical basis for nonlinear active noise control system.
