Design and Implementation of Fuzzy PID Controller for Controlling the Speed of Robotic Vehicle System in MATLAB

Abstract

In recent years, researchers have been developed robotic vehicles for different applications especially in agriculture system. This system consists of a Robotic Vehicle which directs through the area in the required path doing digging as it goes through the path. This paper includes the modeling, design and analytical results of fuzzy PID and PID controller for tracking the speed of the robotic vehicle. The proposed controller was employed to track the desired speed and tracks the direction of the robot vehicle. Ziegler Nicholas and Auto tune based PID algorithm have been used by some authors to find the tuning parameters of P, PI and PID Controllers for achieving the desired set point. The Conventional PID and fuzzy PID algorithms are modelled and simulated in the MATLAB environment using programming code and Simulink. Finally, the performance assessment is contrasted with standard controller PID and fuzzy PID. Fuzzy PID controller tracks the desired speed of robotic vehicle with accuracy in performance indices as compared to conventional PID controller, specified by the designer.
