recommendations! Published in 2018 at "Nonlinear Dynamics"

DOI: 10.1007/s11071-018-4476-7

Abstract: Precise model-based control of parallel robots necessitates an analytically accurate and consolidated model of the robotic platform. Lack of accuracy in modeling causes lots of dynamic uncertainties. This fact can result in higher control gains… read more here.

DOI: 10.1016/j.mechmachtheory.2019.01.023

Abstract: Abstract In this paper we propose a modeling strategy for Cable Driven Parallel Robots (CDPRs) that - given their complexity - are typically addressed using simplified analysis, therefore neglecting relevant dynamics. Specifically, the finite element… read more here.

recommendations! Published in 2020 at "Mechanism and Machine Theory"

DOI: 10.1016/j.mechmachtheory.2020.103895

Abstract: Abstract The elastodynamic analysis of parallel robots still has limitations related to the difficulty of including parts with several input/output nodes. This results in the impossibility of considering fully flexible parallel mechanisms and, therefore, most… read more here.

DOI: 10.1109/tii.2023.3285038

Abstract: In cable-driven parallel robots (CDPRs), the controller should generate positive output forces, as cables only support tensile forces. In fully constrained CDPRs, positive tension distribution in cables is guaranteed using optimization-based techniques, which have unpredictable… read more here.
