Dynamic Modelling and Control Design for a Vehicle in its Longitudinal Motion

Abstract

Background/Objectives: The purpose of developing a model based control study is to understand the longitudinal dynamics in detail. This paper develops mathematical model of longitudinal dynamics of the vehicle and develops a suitable control methodology to have a reliable safe system. Methods/Statistical Analysis: Here the longitudinal dynamics of the system is modeled using white box modeling and suitable PID control algorithm is developed to have a stable dynamics of the systems. To develop the required model Physical laws of equations are used. Findings: For a tuned PID controller, the system stayed within the set point of acceleration and the change in throttle has not affected the system’s velocity and acceleration. Applications/Improvements: This model can be imparted in the driverless car models for complete analysis. Modern control methodologies can be developed for the developed model to have a better performance.Keywords: Longitudinal Dynamics, Longitudinal Motion, Mathematical Model, Physical Laws of Equations, PID Control, White Box Modeling
