In this model, the Concentration controller and Temperature controller both
depend on the output concentration Cr. To set up this gain-scheduled system for tuning,
you linearize the plant at a set of steady-state operating points that correspond to
different values of the scheduling parameter Cr. Sometimes, it is convenient to use a
separate model of the plant for trimming and linearization under various operating
conditions. For example, in this case, the most straightforward way to obtain these
linearizations is to use a separate open-loop model of the plant, rct_CSTR_OL.
mdl_OL = 'rct_CSTR_OL';
open_system(mdl_OL)
