This project presents that Wireless Power Transfer (WPT) systems using resonant topologies, such as the LCC–LCC configuration, offer high efficiency and stable performance for applications including electric vehicles and automated systems. However, variations in coupling and load changes introduce control challenges that affect output voltage stability. This project presents the design and evaluation of an Active Disturbance Rejection Control (ADRC) strategy enhanced with a Super-Twisting Sliding Mode Controller (STSMC) for an LCC–LCC WPT system. The proposed controller aims to improve dynamic response, reduce overshoot, and enhance robustness against disturbances and parameter uncertainties. A comparison with a conventional Proportional-Integral (PI) controller is performed to assess settling time, stability, and voltage regulation under varying load conditions. The STSMC-based ADRC controller achieves faster transient response and superior steady-state voltage regulation compared to the PI controller, demonstrating its effectiveness for reliable and efficient WPT applications.
