| Summary: | DC–DC converters are extensively utilized in renewable energy systems because of the flexibility in their output voltage and their good conversion efficiency. The design of an adaptive sliding mode controller is proposed in this paper for a buck converter system in the presence of load variations, power disturbances, and model uncertainties. The adaptive control law is designed based on the Lyapunov stability criterion and updated online according to variations in the load and external disturbances. The elimination of the chattering mechanism and robustness of the overall system is confirmed. Simulation results indicate better voltage regulation and disturbance rejection for the proposed adaptive controller as compared to the traditional control algorithms. |
