Projektakademie Medizintechnik: Biosignal based prediction of joint movements for mechatronic support systems with adaptive multi domain models

拟议项目旨在通过扩展神经仿生学和生物力学模型拓扑结构来优化关节肌肉模型的精度，以减少身体支撑设备（例如矫形器）操作期间生物和技术系统运动之间的相移。特别是在非常慢（直到完全停止）和非常快的运动中，当前模型失败。这可以通过整合摩擦学模型（刷毛、静摩擦、摩擦、摩擦效应等）来改善。此外，黑盒方法将被应用于识别未知的生物学方面，并将其表示为部分模型。开发的模型主要由肌电信号驱动，并将与其他信号源（器械和生物系统之间的机械压力等）融合。学习和优化方法用于在线调整模型。

The proposed project is supposed to optimize the precision of joint-muscle-models by expanding the neurobionic and biomechanic model topology to reduce the phase-shift between the movement of the biological and technical system during operation of body support devices (e.g. orthosis). Especially during very slow (up to complete stop) and very fast movements, current models fail. This can be improved by the integration of tribological models (bristle, stiction, friction, hysteresis-effects etc.). Additionally, black-box approaches will be applied to identify yet unknown biological aspects and represent those as partial models. The developed models are mainly driven by emg-signals and will be fused with additional signal sources (mechanical pressure between device and biological system etc.). Learning and optimization methods are used to adapt the models online.
