A fractional order viscous friction model in robotic joints
(Beograd : Srpsko društvo za mehaniku, 2019)
The fractional calculus and the calculus of variations are utilized to model and control
complex dynamical systems. Those systems are presented more accurately by means of fractional
models. In this paper, dynamic model ...
