ABSTRACT: Fractional order controllers have been used intensively
over the last decades in controlling different types of processes. The main
methods for tuning such controllers are based on a frequency domain approach
followed by optimization routine, generally in the form of the Matlab fminsearch, but also evolving to more
complex routines, such as the genetic algorithms. An alternative to these time
consuming optimization routines, a simple graphical method has been proposed.
However, these graphical methods are not suitable for all combinations of the
imposed performance specifications. To preserve their simplicity, but also to
make these graphical methods generally applicable, a modified graphical method
using a very straightforward and simple optimization routine is proposed within
the paper. Two case studies are presented, for tuning fractional order PI and
PD controllers.
