This study deals with a generalised version of lead/lag compensators known as fractional‐order lead/lag compensators. Exact and simple formulas are found for designing this introduced type of fractional‐order compensators in order to provide the required magnitude and phase at a given frequency. Also, the region in the phase‐magnitude plane, which is accessible by these compensators, is analytically found. Moreover, numerical examples and experimental results are presented to show the applicability of the achievements of this study in control system design.
