Fractional modeling applied to tilting-pad journal bearings

Tilting-pad journal bearings can be found in a variety of industrial applications due to their stabilizing effects and damping behavior. Reliable mathematical modeling is demanded to analyze and control those dynamical systems. This paper adopts a fractional approach to extend an extant mathematical model of test rig for active tilting-pad bearings. Along with related results, the theoretical framework here presented may contribute to better understand such dynamic behavior, possibly supporting the development of more efficient control strategies for this important mechanical system.
