This study with the aim of monitoring the solar cell output voltages, the battery, the capacitor bank and the DC busbar, and detecting possible faults in a well-timed mode, the optimal optimizer-controller for a small DC network separated from the network is developed through utilization of the State-Dependent Riccati Equation (SDRE) method. In the development of SDRE observer–controller, modeling the diverse operational dynamic behavior of the microgrid is carried out through a nonlinear model. Uncertainty in system parameters and measurement noise are not ignored in the evaluation of the studied microgrid. The capability of the applied method in distinguishing faults in a well-timed mode is confirmed through the outcomes of the simulations. To elaborate, the disturbance is not recognized as a fault which corroborates that, even in this condition, the progressive controller is efficient and resistant.
