Set-point weight tuning rules for fractional-order PID controllers
MetadataShow full item record
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. © 2012 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society.

Padula, Fabrizio; Visioli, A. (2017)© 2017 IEEE. This paper investigates the fragility (both from the stability and performance point of view) of (optimally tuned) fractional-order P(I)D controllers applied to integral processes. Indeed, the effects of the ...
Padula, Fabrizio; Visioli, A. (2011)In this paper we present a set of tuning rules for standard (integer-order) PID and fractional-order PID controllers. Based on a first-order-plus-dead-time model of the process, the tuning rules have been devised in order ...
