Use of Model Predictive Control to Eliminate Split Ranged Control

Terry described an innovative technique of using the PID block for combining split ranged control and valve position control (see Terry’s Oct 16 entry). This technique eliminates the limit cycle at the split range point caused by the increase in nonlinearities and the decrease in resolution imposed by backlash, backfilled pipes and dip tubes, rangeability …
