This paper contributes to the design of a fractional order (FO) internalmodel controller (IMC) for a first order plus time delay (FOPTD) process modelto satisfy a given set of desired robustness specifications in terms of gainmargin (Am) and phase margin (Pm). The highlight of the design is the choice ofa fractional order (FO) filter in the IMC structure which has two parameters(lambda and beta) to tune as compared to only one tuning parameter (lambda) fortraditionally used integer order (IO) filter. These parameters are evaluatedfor the controller, so that Am and Pm can be chosen independently. A newmethodology is proposed to find a complete solution for controller parameters,the methodology also gives the system gain cross-over frequency (wg) and phasecross-over frequency (wp). Moreover, the solution is found without anyapproximation of the delay term appearing in the controller.
