摘要
Abstract
With the high-speed development of magnetic levitation trains,the requirements of their levitation system for the current loop response speed and accuracy keep increasing.In this paper,the active disturbance rejection control ( ADRC ) technology is applied in the control of a suspension chopper.First,the mathematical models of a levitation system of magnetic levitation train and a suspension chopper are elaborated upon.Then,the basic structure and working principle of an ADRC controller are introduced,and an ADRC current following model in the suspension chopper is designed.Finally,the system is simulated by changing the parameters of the suspension chopper model and applying external disturbances,and a comparison with the traditional proportional-integral ( PI ) control is performed.Results show that ADRC has a good current following effect on the suspension chopper,as well as good anti-disturbance and robustness to external disturbances and changes in the object model parameters.In addition,the ADRC algorithm reduces the dependence on mathematical models,providing an optimized solution for the control of the suspension chopper.关键词
