Model Parameters Identification and Backstepping Control of Lower Limb Exoskeleton Based on Enhanced Whale Algorithm

Shi, Yan; Kou, Jiange; Chen, Zhenlei; Wang, Yixuan; Guo, Qing

2024 Chinese Journal of Mechanical Engineering

doi:10.1186/s10033-024-01008-6

Exoskeletons generally require accurate dynamic models to design the model-based controller conveniently under the human-robot interaction condition. However, due to unknown model parameters such as the mass, moment of inertia and mechanical size, the dynamic model of exoskeletons is difficult to...
