In this article, an unknown system dynamics estimator-based impedance control method is proposed for the lower limb exoskeleton to stimulate the tracking flexibility with the terminal target position when suffering parametric inaccuracies and unexpected disturbances. To reinforce the robust performance, via constructing the filtering operation-based dynamic relation, i.e., invariant manifold, the unknown system dynamics estimators are employed to maintain the accurate perturbation identification in both the hip and knee subsystem. Besides, a funnel control technique is designed to govern the convergence process within a minor overshoot and a higher steady-state precision. Meanwhile, an interactive complaint result can be obtained with the aid of the impedance control, where the prescribed terminal trajectory can be adjusted into the interaction variable-based target position by the force–position mapping, revealing the dynamic influence between the impedance coefficient (stiffness and damping) and the adjusted position magnitude. A sufficient stability analysis verifies the ultimately uniformly bounded results of all the error signals, and even the angle errors can be regulated within the predefined funnel boundary in the whole convergence. Finally, some simulations are provided to demonstrate the validity and superiority including the enhanced interaction flexibility and robustness.

哲学逻辑的模态认知与本质主义关系探析

所谓模态就是指事物或认知的必然性和可能性等这类性质。所谓本质,在某种意义上就是指存在于有关客体或者对象中的必然真。由此,人们不能因为事物或对象的本质、本质属性,有时具有相对性和多样性而难以认知,就否定事物或对象具有本质或... 详细信息

所谓模态就是指事物或认知的必然性和可能性等这类性质。所谓本质,在某种意义上就是指存在于有关客体或者对象中的必然真。由此,人们不能因为事物或对象的本质、本质属性,有时具有相对性和多样性而难以认知,就否定事物或对象具有本质或本质属性。文章在阐述模态、模态认知和本质主义等问题的基础上,探析了哲学逻辑的模态认知与本质主义的关系,以及它们在认知科学中的作用与意义。

认知就是人们认识看待这个世界的方式。如果这里的"人们"是在不同的文化圈与不同的价值链之中,那么,他们对同一事物的认知就会有不同程度的差异,甚至相互矛盾。广义地讲,可能世界是指能无矛盾地设想的世界,而这里的"可能"又有逻辑可能与形而上学可能之分。"逻辑可能"是指事态的出现不会导致逻辑矛盾,不会违反逻辑规律;而"形而上学可能"是指事态的出现不与相关事物的存在、本质属性发生矛盾或不一致。当下人类命运共同体的愿景,既是超验理想也是经验层面的利益共同体。实现这一愿景就在于化解认知矛盾,进而通过文化互通建立起人类的价值共识。可能世界理论的智慧在于,可能世界的语言不是实在论的,它是一种正确性与合理性的代名词。从现实世界就是实现了的可能世界看,人与自然和谐共生以及人类自身构建和合社会的理想,起点就在于人们的认知矛盾能够得以化解,进而形成人们相互之间的价值共认,如此人们设想的可能世界才有现实的可能性。

时态与模态总是相互依存的,主客时间是主体的先天直观形式,主观模态则是对事物的模态认知。那些不断指向可能"将来"的"现在",总是携带着必然的"过去",并且,必然的"过去",也通过"现在"与可能的"将来"勾连起来。因此,人们常说:了解历史就是为了现在更好地掌握将来。阐明了存在与时间、模态与时态等问题,主、客观时间的特征和时态因素与模态因素的关系就得以显现,对时态命题与模态命题的认知也可以深化一步了。
