| 英文摘要 |
| Modular multilevel converter-railway static power conditioner (MMC-RPC) is a coupled multi-variable nonlinear
system, and the traditional direct power control method of PI control is difficult to achieve precise decoupling of the
system control. In this paper, a feedback linearized direct power control method based on linear extended state observer
is proposed. According to the Lie derivative, the MMC-RPC two-input/two-output power affine model is constructed, and
an accurate feedback linearized power decoupling controller is designed. Aiming at the influence of uncertain factors and
other disturbances on the effect of precise feedback linearization control, a linear expansion state observer is designed to
observe and compensate the disturbances, and to achieve precise power tracking control. Finally, the proposed control
method is validated by building a simulation model on the MATLAB/Simulink platform. |
