Vehicle Speed Control for Autonomous Vehicle using PID Controller

Abstract

This project presents a real time reading of Proportional Integral Derivative (PID) controller tuning. The system will control the output speed of the vehicle based on the given input speed by implementing the PID controller. The controller helps in ensuring that the output speed achieves the same as the input speed given and does not depart. The speed of car is controlled by controlling a linear motor that is attached to a current sensor and an incremental encoder as a feedback to calculate speed. The output reading of speed is in km/h. Raspberry Pi 3B+ is used as microcontroller and python language is used in order to program the vehicle speed. The vehicle is tested and PID parameter are calculated. The system is then run by using PID parameter and it shows that expected PID controller is stable and able to control the car’s speed.
