Haptic Rendering of Fractional-Order Viscoelasticity: Passivity and Rendering Fidelity
A recent study released on arXiv examines the passivity and rendering efficiency of fractional-order viscoelastic models utilizing finite-memory discretization. This research formulates closed-form equations to guarantee haptic rendering passivity through a fractional-order standard linear solid model, employing the Grunwald-Letnikov derivative alongside short-memory discretization. Additionally, it offers symbolic representations for the effective stiffness and damping of these models. The established passivity criteria create a comprehensive framework that expands upon earlier findings, with potential uses in medical training and the realistic modeling of biological tissues.
