FEBRUARY 2009 – BATCH CONTROL GETS EASIER
Loop tuning package doesn’t demand steady-state operation.
The nonlinear dynamics of most exothermic and endothermic batch reactions require expert attention to assure quality production. For instance, introducing reactants often results in dramatic swings in temperature. Maintaining production tolerances in such an environment tests the effectiveness of any proportional-integral-derivative (PID) controller and the associated tuning parameters.
