Nonlinear Active Disturbance Rejection Controller for Hybrid Microgrid

Improved Nonlinear Active Disturbance Rejection Controller (INLADRC) for a Hybrid Microgrid with Communication Delay using MATLAB/Simulink simulations. The reference paper is provided for further details.

The INLADRC technique incorporates a nonlinear extended state observer (NESO) to estimate system states and a nonlinear controller to cancel generalized disturbances affecting the system. To mitigate the impact of communication delay in the hybrid microgrid, an auxiliary structure is introduced, ensuring synchronization between observer inputs.

The MATLAB simulation includes a dynamic model of a hybrid microgrid controlled using both the nonlinear controller and conventional PI controllers.
