Özet

This paper presents a hybrid fuzzy-logic trajectory control scheme for a 2-DOF robotic manipulator, validated through both simulation and experimental studies. While conventional PID controllers provide satisfactory steady-state accuracy, they often fail under nonlinear dynamics and parameter uncertainties. To overcome these limitations, a fuzzy inference system is employed to adaptively tune PID gains in real time, using error and error derivative as inputs. The controller is first implemented in a custom simulation environment and subsequently deployed on a physical manipulator prototype. Comparative results demonstrate that the hybrid fuzzy-PID controller significantly reduces overshoot, decreases root-meansquare trajectory error, and achieves smoother torque profiles compared to a baseline PID controller. These findings highlight the potential of fuzzy-based hybrid control for robust and precise robotic manipulator trajectory tracking.
