Fuzzy Logic Control – Example

In this fuzzy logic control workshop contained in Chapter 6 of Advanced Control Foundation – Tools, Techniques, and Applications, the control performance of fuzzy logic control is
be compared to the performance of PID control. For this example, the control objective is to reach setpoint in minimum time with no overshoot.

Two identical process heaters are simulated with PID and fuzzy logic control as illustrated below.

To illustrate the difference in control performance the Integral Absolute error is calculated for the PID and Fuzzy Logic control. Also, the ability is provided to introduce setpoint changes into the control and unmeasured load disturbance into the process simulation. To see the workshop solution you may access the book’s web site.
