ABSTRACT: Wind turbine blade vibrations induced by unsteady aerodynamic loading remain a critical challenge in modern wind energy systems, affecting efficiency, structural integrity, and service life. These effects are amplified under gusty and turbulent wind conditions, leading to higher stress levels and reduced operational reliability. Although several damping strategies exist, conventional systems are often constrained by added mass, slow transient response, high energy consumption, and maintenance requirements, while inconsistent modeling approaches hinder fair comparison. In response to these challenges, this study developed a unified MATLAB/Simulink framework to evaluate a Lorentz torque damper against nine conventional damping techniques under identical conditions, with a focus on settling time as the primary performance metric. The results show that the Lorentz torque damper achieves a 22% - 67% reduction in settling time and a 62% - 72% reduction in RMS vibration compared with conventional systems. The model validation yielded a natural frequency of 2.212 Hz, closely matching the benchmark value of 2.100 Hz with a 5.32% error. Overall, the findings confirm that the Lorentz torque damper provides an efficient, lightweight, and cost-effective solution for enhancing wind turbine vibration control and long-term operational performance.
