OpX Control has optimized/tuned over 2,225 control loops in 96+ weeks at over 47 ethanol plants, with an average 48.7% reduction in range of control /deviation from setpoint. This is done through model-based loop/valve tuning, identification of valve problems (stiction/hysteresis) measurement problems, and tuning to break interactions. Advanced Regulatory Control (ARC) strategies have been implemented at many of these sites, effectively replacing APC. ARC include functions done in the DCS such as feed-forward, constraint, decoupling control, gain-scheduling, and set point ramping.
