Case Study:
For better understanding of both methods used for PID tuning and optimization, we will use the example of industrial batch reactor, as illustrated in Figure 3. In this example the temperature inside the reactor volume is measured and controlled by a temperature controller (TC) manipulating the steam control valve which enters the jacket of a batch reactor. The purpose of this TC is to have stable and tight control of a reactor temperature. The temperature inside the reactor can vary due to different operating SPs, steam pressure and temperature fluctuations (disturbances ). Therefore, the goal is to tune this TC based on different SP and disturbances changes.
