Performance analysis of the fractional-order vehicle mechatronic ISD suspension with parameter perturbation

Abstract

This paper concerns the performance analysis of a fractional-order vehicle mechatronic ISD suspension with parameter perturbation. A dynamic model of the vehicle mechatronic ISD suspension based on a fractional-order electrical network is constructed. The superiority of the vibration isolation performance of the fractional-order ISD suspension is demonstrated, and the dynamic performance of the suspension is analyzed considering perturbation of parameters. Results show that the inertance has an important role when the frequency is above 10 3 Hz, and the fractional inductance order and fractional capacitance order have significant impact in the frequency range of 10 −2 Hz to 10 2 Hz.

“…In recent decades, fractional calculus has been increasingly used in many scientific researches. Fractional derivatives are widely utilized in mechanics of materials, control systems, mechatronics, thermoelasticity, signal and image processing, engineering biology and many other (Freundlich, 2016; Podlubny, 1999;Shen et al, 2022;Sumelka, 2016;Sumelka et al, 2020;Tayel and Hassan, 2019). Since, fractional derivatives are not local, they are used for modeling of non-local phenomena i.e.…”

Optimal Design and Dynamic Performance Analysis of Vehicle Suspension Employing an Eccentric Inerter

“…However, most studies in the field of ISD suspension have only focused on the optimization of the suspension structure and improvement of the control strategy [26][27][28][29], and few researchers have treated to improve the structure of the inerter itself in much detail. It can be seen from the existing research that the structure of the inerter is diverse, and most structures tend to be idealized, ignoring the presence of eccentric devices in many scenarios.…”
