Different control strategies have been proposed in the literature to achieve their objectives, with the most commonly used being the PID (Proportional-Integral-Derivative) controller, despite its inaccuracies resulting from the mathematical model. To improve the PID control, fractional control can be used. This paper proposes an improvement to the PID control of a two-degree-of-freedom manipulator arm by incorporating a fractional integration operator, namely Euler's Gamma function, in the controllers. The drawbacks observed with the PID controller have been eliminated by using the optimized PID controller (PIDG) with Euler's Gamma functionentwo DOFManipulator armPath trackingPID controlFractional controlEuler Gamma functionArticle
