The problem of tuning the set‐point weight for fractional‐order proportional‐integral‐derivative ( FOPID ) controllers is addressed in this paper. Tuning rules are given in order to use the set‐point weight effectively for the recovering of the set‐point following performance when the FOPID controller is tuned in order to optimize the load disturbance rejection performance. Self‐regulating, integral and unstable processes are considered. Simulation results show the effectiveness of the proposed tuning rules and the comparison with integer‐order PID controllers.
