Protecting Your Back – the Cautious Approach and Fast Getaway Scenario

While approaching an optimum something can sneak up that catches the loop off guard. Because of the deadly foe dead time, by the time the loop sees and reacts, it may be too late, particularly if it was blind sided. The classic example is compressor anti-surge control. When moving to a lower discharge pressure or …

How to Succeed – Part 10

We conclude with a summary on how you can avoid bursts of oscillations, get to setpoint faster, choose the right execution time and filter, coordinate the speed of loops, optimize operations without while protecting equipment, provide a consistent flow response for model predictive control, eliminate limit cycles, and improve analyzer and wireless control loops (all …

Dynamic Reset Limit

I just realized external reset is the key to sustainable manufacturing and in particular abnormal situation prevention and optimization. I knew the PID option “dynamic reset limit” where the external reset signal is a secondary loop PV, variable frequency drive speed, or control valve position, was important. I demonstrated in Deminar # 3 how dynamic …
