Abstract : "This paper proposes a generalized and simple analytical method to design robust fractional-order lead
compensator (FOLC). The aim of the proposed fractional-order compensator is to adjust the system’s Bode phase
curve to achieve the required phase margin at a specified frequency. The structure selected in this paper is more
generalized and novel. It is easy to implement for a real world application. The method proposed is frequency
domain and parameters of fractional compensator are selected from the plant information and specifications. This
FOLC satisfies the specifications on static error constant, Kss, gain crossover frequency, wc and phase margin, φm.
The applicability of the proposed method is demonstrated with illustrative examples. From the simulation results
obtained, it is observed that FOLC gives robust and stable performance as compared to existing FOLC and integerorder
lead compensator (IOLC)."
