中文摘要
      为了使PWM变换器能够实时精准控制输入电流, 在能馈型电子负载的实际应用中, 针对前级电流跟踪控 制中采用的双抛物线电流控制算法, 分析了引起双抛物线幅值波动的不同因素, 进而影响电流的跟踪效果, 提出了 一种基于观测补偿的幅值可变的双抛物线电流控制方法. 本文采用了牛顿迭代法实现对下一周期值的观测估计, 并且通过周期和幅值的关系来确定反馈值, 对下一时刻的幅值进行补偿. 最后本文通过仿真验证了该方法的有效 性, 实现了周期恒定的电流实时跟踪.
英文摘要
      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 engineering 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 proposed. 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.
