Fractional order system model represents the plant more adequately than integer order model. Fractional order controller is naturally the suitable choice for these fractional-order models as well as it is widely used for integer order model also. The significance of fractional order control is that it is a generalization of classical control theory. Most of the works in fractional order control systems are in theoretical nature and controller design and implementation in practice are very small. In this paper, stability and performance analysis of fractional order control systems are briefly explained. To show the effectiveness of the article, the paper demonstrates illustrative design examples. The major purpose of this paper is to draw attention to the non-conventional way of system analysis and its control.
