Abstract—This paper presents a novel tuning algorithm for fractional order IMC controllers for time delay processes. The tuning algorithm is based on computing the equivalent controller of the IMC structure and imposing frequency domain specifications for the resulting open loop system. A second order time delay process is used as a case study. An integer order IMC controller is designed, as well as a fractional order IMC controller. The simulation results show that the proposed fractional order IMC controller ensures an increased robustness to modeling uncertainties.
