The control of dual parabola algorithm technology with variable amplitude based on period observation
摘要
Abstract
In order to make the current track the reference current accurately in real-time for PWM converter current control technology, the different factors were analyzed what impact the amplitude fluctuations applying on actually en-gineering project of energy-feedback electronic load based on the dual parabolic current control(DPCC)algorithm. The amplitude fluctuations of DPCC caused control deviation, and an amplitude variable of DPCC control method was pro-posed. With state observation based on Newton iteration realized the next cycle value estimated,and the feedback value compensated the amplitude at the next period so that the relationship between amplitude and period was determined.At the end of the paper,the proposed method was verified through the simulation,and realized real-time tracking the current with constant period.关键词
