The study of doubly-fed generator grid side PWM high-order sliding mode control
摘要
Abstract
Aiming at the problem of parameters changing of doubly-fed generator and other external interference influ-ence on the grid side PWM, the traditional PI control did not behave very well in terms of the response speed and con-trol precision on performance.For the above problems, the sliding mode variable structure control showed perfect ro-bustness.In order to improve the deficiency of PI controller, this paper put forward the high-order sliding mode con-trolling the grid side PWM.First of all, this paper introduced the mathematical model of doubly-fed generator of the grid side PWM, and proposed the high-order sliding mode variable structure strategy.From the simulation results, we could summarize that comparing with the PI controller, high-order sliding mode control could adjust the DC bus volt-age more rapidly and show better dynamic characteristics.关键词
