Chapter 6 Applied Instructions Note: The example is only for reference. Users have to tune the parameters properly according to the practical condition of the control system. Sample 1: Using the automatic tuning function to control the temperature Purpose: Using the automatic tuning function to calcaulte the most appropriate parameters for the PID temperature control Explanation: Due to the fact that users may not be familiar with the characteristics of the temperature environment which is controlled for the first time, they can use the automatic tuning function to make an initial adjustment ( PID_MODE is set to 1). After the tuning of the parameter is complete, PID_MODE is set to 0.
The controlled environment in this sample is an oven. The program example is as below. The experimental result of the automatic tuning function is shown below. 6-174
