Many individuals experience finger loss due to congenital deformities or accidents, significantly impacting their ability to perform daily tasks and their self-confidence. This thesis develops a nonlinear mathematical model for a prosthetic finger with three degrees of freedom. It applies the Lagrange and Euler-Lagrange equations for accurate dynamic simulation and employs Classical Synergetic Control (CSC) and Adaptive Synergetic Control (ASC) to manage finger movement. Using Lyapunov's theory, control and adaptive laws were created to ensure system stability. The results showed that CSC and ASC outperformed other control methods in efficiency and provided smooth motion response while achieving the desired position angle without chattering. The CSC and ASC systems provided global stability and flexibility in adapting to parameter changes, enabling precise tracking of the finger's movement. The study also found that ASC outperformed CSC in improving performance by 33%, in terms of tracking time and reducing power consumption. This indicates a promising future for the development of Prosthetic fingers.
