升压型功率因数校正变换器的改进线性自抗扰电压环控制
Modified Linear Active Disturbance Rejection Control-based Voltage-loop Control for Boost PFC Converter
摘要
Abstract
To further improve the anti-interference ability and dynamic performance of a Boost power factor correction converter(Boost PFC),an improved control strategy based on the linear active disturbance rejection control(LADRC)is proposed.The generalized disturbance compensation operator(GDCO)is introduced on the basis of the linear extended state observer(LESO)which realize the observer's fast estimation and compensation of the extended state.The sensitivity of the observer is improved without introducing the high-frequency noise,and increases the degree of freedom for the outer-loop voltage controller.The influence of different GDCO parameters on the anti-interference performance,the dynamic and stable characteristics of the system is discussed in detail,and the parameter selection principle is also given.A 1 kW Boost PFC converter is built.Simulation and Experimental results indicate that,compared with the conventional PI and LADRC outer voltage loop control,the proposed LADRC-GDCO voltage loop control is able to improve the anti-interference ability and the dynamic response with the same current THD value.关键词
