ADVANCED CONTROL TECHNIQUES FOR DC-DC BUCK CONVERTERS: A COMPARATIVE STUDY OF SLIDING MODE AND PID CONTROLLERS

A comparison of sophisticated control systems for a DC-DC buck converter is presented in this research, with particular attention to proportional-integral-derivative (PID) and sliding mode control (SMC) approaches. Improving the converter's resilience and dynamic performance under various input and load scenarios is the goal. Known for its simplicity and ease of use, the PID controller is compared to the SMC method, which has better robustness and disturbance rejection capabilities. The performance of both control systems in terms of output voltage regulation, transient responsiveness, steady-state error, and overall system stability is analyzed and contrasted using the simulation results. For effective power management in DC-DC converters, the study offers insightful information on how to choose the best control strategies.
