Stability of closed-loop fractional-order systems and definition of damping contours for the design of controllers [PDF]

, 2012
Fractional complex order integrator has been used since 1991 for the design of robust control-systems. In the CRONE control methodology, it permits the parameterization of open loop transfer function which is optimized in a robustness context.
