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.

拟议的项目应该通过扩展神经生物和生物力学模型拓扑来优化联合肌肉模型的精度，以减少身体支撑设备运行期间生物学和技术系统运动之间的相变（例如矫形器）。尤其是在非常缓慢的过程中（直至完成停止）和非常快速的动作，当前的型号失败了。摩擦学模型的整合（猪鬃，刻板，摩擦，滞后效应等）可以改善这一点。此外，将采用黑框方法来识别但未知的生物学方面，并将其表示为部分模型。开发的模型主要由EMG信号驱动，并将与其他信号源（设备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。
