With the rapidly development of DC microgrid technology, the stability control of bus voltage in DC microgrid, as the key to the normal and stable operation of DC microgrid, has also become one of the research hotspots; Aiming at the influence of parameter perturbation and load disturbance on the voltage outer loop of DC microgrid bus, a compound controller ESO-NRSMC combining extended state observer (ESO) and new reaching law sliding mode controller (NRSMC) is proposed; The controller adopts a new approach law method to solve the contradiction between chattering and the approach time of sliding mode surface; At the same time, the extended state observer compensates the observed disturbance value into the sliding mode controller to further improve the anti-disturbance ability of the controller; Lyapunov function is also constructed to verify the stability of the designed bus voltage outer loop closed-loop control system; Finally, the simulation shows that the controller ESO-NRSMC can still realize the stable control of DC microgrid bus voltage when the microgrid system parameters change and load disturbance, and has strong superiority and robustness.
