Reducing Vibrations Caused by Sine Path input in a half car model: A PID Control Algorithm

Abstract

This study aims to minimise the vertical displacement and acceleration of a 4-degree-offreedom half-vehicle model, which includes two wheels and a vehicle body, using a PID controller. In this scenario, the vehicle is subjected to a sine wave with an amplitude of 0.05 m. The exposed portion of the vehicle experiences wavelengths of 20 m and 40 m. Furthermore, the study considered two distinct vehicle speeds: 50 km/h and 100 km/h. The study analysed the vertical displacement and acceleration of the vehicle under two different speeds and two sine wavelengths. The implementation of the PID controller resulted in a significant reduction of approximately 80% in these values.
