In recent years, with the development and progress of science and new technology, requirements for control systems are becoming increasingly high, especially in some special fields, such as:viscoelastic material, electrolysis chemistry and so on. The common integer order calculus control theory cannot meet the requirements very well. The fractional calculus theory, especially the fractional calculus

This paper investigates the robust stability and feedback controller design problem of the fractional-order linear systems with nonlinear uncertain parameters. Recently, the fractional-order control systems have attracted increasing interest by more and more scholars.The robust stability analysis and robust controller design issues have been the main contents of the research in the control theory. Most

Fractional order calculus has gained much attention in lots of research areas during recent years. It has also been applied to control area, where fractional order systems attract many research interests. In fact, some actual complicated systems are hard to be modeled as traditional integer order models. While, FOC (Fractional Order Calculus) is a good

Fractional calculus is the calculus whose integration or differentiation order is not conventional integer number but real or even complex one. It is extensiton of integer calculus. Farctional order control, which is established on the idea of fractional order operators and the theory of fractional order dieffrential equations, is now a quite new research direction.
