  • Page 36: Part 6 - Pid Controller Details

    Part 6 – PID Controller Details PID Description PID control, like many other control schemes, are used in chemical control to improve the efficiency of chemical addition or control. By properly tuning the control loop that controls chemical addition, only the amount of chemical that is truly required is added to the system, saving money.
  • Page 37 Part 6 – PID Controller Details Q46F/82 Direct Fluoride Monitor The most notable feature of the algorithm is the fact the proportional gain term affects all components directly (unlike some other algorithms - like the “series” form.) If a pre-existing controller utilizes the same form of the algorithm shown above, it is likely similar settings can for made if the units on the settings are exactly the same.

  • Page 38: Classical Pid Tuning

    Part 6 – PID Controller Details Q46F/82 Direct Fluoride Monitor Classical PID Tuning Unlike many high speed position applications where PID loops are commonly used, the chemical feed application employed by this instrument does not require intense mathematical exercise to determine tuning parameters for the PID.
  • Page 39 Part 6 – PID Controller Details Q46F/82 Direct Fluoride Monitor addition, if a chemical process is not symmetrical, that means it responds differentially to the addition and subtraction of chemical. It is important in these applications to study steady-state impact as well as step-change impact to process changes. In other words, once the process has apparently been tuned under normal operating conditions, the user should attempt to force a dramatic change to the input to study how the output reacts.
