Abstarct: Research in different fields of engineering indicate that the fractional order (FO) dynamics can be used for more accurately model and control of physical phenomena. Thus, design of a suitable controller with regard to model uncertainty and input saturation is one of the key topics of interest to researchers. In this thesis, robust stability analysis of uncertain commensurate FO neutral systems with different time delays and input saturation is studied. The Lyapunov direct method is adopted to analyze the (robust) asymptotic stability of such systems. The conditions for stability are expressed in the form of linear matrix inequalities. Using the derived results, an appropriate state feedback controller is designed. In addition, baxsed on the cone complementarity linearization algorithm, the controller gains are determined to extend the domain of attraction. Simulation results with practical examples are provided, demonstrating good performance of the designed controller
