This paper presents the design and application of fractional single-input-single-output (SISO) controllers to
a grinding mill circuit, which is a multiple-input-multiple-output (MIMO) process. Two kinds of controllers
are presented: fractional order proportional-integral (FOPI) controllers, and a combination of FOPI and
fractional order model reference adaptive controllers (FOMRAC). The parameters of the controller are tuned
using o -line particle swarm optimization. In the presence of disturbances and process noise, the SISO
fractional controllers achieve similar or better performance compared to Linear Model Predictive Control
