吊车双摆系统的仿真 说明了pid控制方法的局限性(Crane double pendulum system simulation illustrates the limitations of pid control)

At this moment, the major obstacle of wide PV system commercialization is the high initial investment cost that stems from the strict grid connection standards and high expectations from the PV system [2], [3]. The grid-connected PV system consists of two parts: PV arrays that convert irradiation to electrical energy, and the converter that feeds the energy into the grid.
