Dynamic Gravity Cancellation and Regulation Control in Robots with Flexible Transmissions: Constant, Nonlinear, and Variable Stiffness

De Luca, Alessandro; Flacco, Fabrizio - Dipartimento di Ingegneria Informatica, Automatica e … - 2010

stiffness (elastic joints), nonlinear flexible, and variable nonlinear flexible transmissions with antagonistic actuation are … analyzed. As a particular case, antagonistic actuation with transmissions having constant but different stiffness is also … the need of any positive lower bound neither on the stiffness nor on the proportional control gain. A Lyapunov-based proof …

Methods to Increase the Robustness of Finite-Volume Flow Models in Thermodynamic Systems

Quoilin, Sylvain; Bell, Ian; Desideri, Adriano; … - In: Energies 7 (2014) 3, pp. 1621-1640

This paper addresses the issues linked to simulation failures during integration in finite-volume flow models, especially those involving a two-phase state. This kind of model is particularly useful when modeling 1D heat exchangers or piping, e.g., in thermodynamic cycles involving a phase...
