摘要: This paper introduces a novel chattering-free terminal sliding mode control (SMC) strategy to address chaotic behavior in permanent magnet synchronous generators (PMSG) for offshore wind turbine systems. By integrating an adaptive exponential reaching law with a continuous barrier function, the proposed approach eliminates chattering and ensures robust performance under model uncertainties. The methodology combines adaptive SMC with dynamic switching to estimate and compensates for unknown uncertainties, providing smooth and stable control. Finally, the performance and effectiveness of the proposed approach are compared with those of a previous study.
