Analysis of the Stability of the Active Disturbance Rejection Control Technology of Multi -Variable Internal Mode Structure

In the multi-variable and strong coupling merger network system, in order to improve the stability performance of the DC bus voltage of the power grid, this article proposes that the current inner ring is based on the inner mode control structure. Analyze the stability of the active disturbance rejection controller, so that the stability and dynamic performance of the system can be quickly reached to the optimal state.
