A MATLAB toolbox for multivariable linear fractional-order control systems

In this paper, an extended version of the FOTF Toolbox is presented which can be used to handle multivariable fractional-order transfer function matrices. A good interface is provided on top of the well-established MFD (Multivariable Frequency Design) Toolbox, which enables the users to perform frequency domain analysis and design of linear fractional-order systems. An illustrative example is also provided in the paper to show the applications of modeling, analysis and design of fractional-order systems with the proposed toolbox.
