GAMM-Mitteilungen, Volume 46, Issue 1, March 2023., 2023 Abstract Compared to conventional robots, flexible manipulators offer many advantages, such as faster end‐effector velocities and less energy consumption. However, their flexible structure can lead to undesired oscillations. Therefore, the applied control strategy should account for these elasticities. A feedforward controller based on an inverse model

Nominal geometry and force measures for solids and fluids
International Journal of Mechanical System Dynamics, Volume 2, Issue 3, Page 249-252, September 2022., 2022 Abstract Understanding solid‐ and fluid‐inertia forces and their coupling with the gravity potential in complex motion scenarios is necessary for evaluating system stability and identifying root causes of system failure and accidents. Because solids and fluids have an infinite number of degrees of freedom and distributed inertia and elasticity, having ...

Multibody system transfer matrix method: The past, the present, and the future
International Journal of Mechanical System Dynamics, Volume 2, Issue 1, Page 3-26, March 2022., 2022 Abstract The multibody system transfer matrix method (MSTMM), a novel dynamics approach developed during the past three decades, has several advantages compared to conventional dynamics methods. Some of these advantages include avoiding global dynamics equations with a system inertia matrix, utilizing low‐order matrices independent of system degree of ...

IET Electrical Systems in Transportation, Volume 11, Issue 3, Page 269-277, September 2021., 2021 Abstract To improve the carrying capacity, double pantographs are normally used to collect the electric current from the catenary. The mechanical wave excited by the leading pantograph affects the contact of the trailing pantograph and the contact wire, which usually deteriorates the current collection quality.

Stable Inversion for Flexible Multibody Systems Using the ANCF
PAMM, Volume 20, Issue 1, January 2021., 2021 Abstract Flexible robots are often non‐minimum phase systems. Thus, their inverse model must be computed by stable inversion. Here, a simplification to the stable inversion process is proposed, which enables its application to complex underactuated multibody systems.
