中文摘要
      本文采用动态状态反馈控制方法研究在外界干扰下带LCL滤波器的三相并网逆变器的鲁棒电流跟踪控制问题. 首先,本文构建内模用于学习并网逆变器在稳态下的状态和输入信息.其次,利用内模原理,基于一些合适的坐标变换 将跟踪控制问题转化为鲁棒镇定控制问题.然后,设计一种动态状态反馈控制律来处理这一鲁棒镇定问题,从而得到三 相并网逆变器的鲁棒电流跟踪控制问题的解.该控制方法能够保证闭环系统的渐近稳定性.最后,通过几组仿真验证提 出的控制方法的有效性,并将其与前馈控制方法做对比,以验证本文提出的方法对不确定参数的鲁棒性.
英文摘要
      This article investigates the robust current tracking control problem of three-phase grid-connected inverters with LCL filter under external disturbance by a dynamic state feedback control method. First, this paper constructs an internal model to learn the information of the states and input of the grid-connected inverter under steady state. Second, by utilizing the internal model principle, the paper turns the tracking control problem into the robust stabilization control problem based on some appropriate coordinate transformations. Then, The paper designs a dynamics state feedback control law to deal with this robust stabilization problem, and thus the solution of the robust current tracking control problem of three-phase grid-connected inverters can be obtained. This control method can ensure the asymptotic stability of the closed loop system. Finally, the paper illustrates the effectiveness of the proposed control approach through several groups of simulations, and compares it with the feedforward control method to verify the robustness of the proposed control method to uncertain parameters.
