  A novel toolbox named FLOreS is presented for intuitive design of fractional
order controllers (FOC) using industry standard loop shaping technique. This
will allow control engineers to use frequency response data (FRD) of the plant
to design FOCs by shaping the open loop to meet the necessary specifications of
stability, robustness, tracking, precision and bandwidth. FLOreS provides a
graphical approach using closed-loop sensitivity functions for overall insight
into system performance. The main advantage over existing optimization
toolboxes for FOC is that the engineer can use prior knowledge and expertise of
plant during design of FOC. Different approximation methods for fractional
order filters are also included for greater freedom of final implementation.
This combined with the included example plants enables additionally to be used
as an educational tool. FLOreS has been used for design and implementation of
both integer and fractional order controllers on a precision stage to prove
industry readiness.
