Compared to the conventional PID controller, main advantages of the RTD-A controller are its transparent parameters, convenient adjustment and implementation. The RTD-A controller is extended to its fractional form and compared with fractional controller tuned by Z-N method and PID con- troller tuned by Wang-Juang-Chan method. Proposed fractional predictive controller shows good performances in set-point tracking, disturbance rejection and robustness. Simulation results show the validity of the proposed method.
