3.4 Tuning the controller

This controller is shipped with parameters set for commercial rice cookers. You can try to

use these settings for other cooking device also because they are suitable for a typical

slow response and balanced system. If you feel the performance is not ideal, you can try

to use the recommended PID parameters listed in Table 1. These are the parameters we

obtain from tuning the system manually. If your cooker is not listed in the Table 1 of our

pre-selected cookers, or the PID parameters we provided are not working for your liking,

you can use the auto-tuning function to let the controller to determine the PID

parameters automatically. You can also manually tune the PID parameter if you are

familiar with PID control technology. To activate the auto-tuning processes or change the

P, I and D parameters, please see the next section and Figure 7.
