Analysis of Quarter-Car Suspension Dynamics in Sports Cars with PID Control

Abstract

The analysis and modeling of a sports cars suspension using a PID controller aims to minimize vibrations, effectively shifting the system from underdamped to nearly critically damped, thus enhancing comfort. This research emphasizes the significance of the mass-spring-damper model in suspension analysis, particularly highlighting the role of PID control in reducing vibrations for improved user comfort in sports cars. The comprehension of mechanical system dynamics is facilitated by utilizing the mass-spring-damper system as a mathematical tool, drawing parallels between suspensions and such systems, where energy is stored, similar to the shock absorption in a suspension. Ride comfort, a pivotal aspect of vehicle performance, often faces disruption due to road-induced vibrations, which suspensions manage to mitigate discomfort and disorder. Through quarter-car models, this research delves deep into suspension dynamics, contributing to optimizing suspensions for elevated ride comfort, stability, and enhanced handling.
