PID tuning issues during slope control
Thread Content
In fine chemical manufacturing, operations such as heating and cooling are common, and automatic control may require what is known as ramp control. During the heating process, are the PID parameters of the controller fixed or variable? Is it set in the program?
During the slope control process, the PID parameters of the controller can be fixed or variable, depending on the requirements and design of the control system. A common practice is to gradually increase or decrease the values of the PID parameters during the temperature rise process, in order to adapt to the changes in temperature. The setting of these parameters can be done within the program of the control system, usually by adjusting the numerical values of the parameters in the program code. Additionally, advanced controllers such as adaptive controllers or model predictive controllers can be used to adjust parameters online based on real-time feedback signals and the target temperature. In summary, in slope control, the setting of PID parameters can be adjusted according to the control requirements, and they can be set within the program or automatically adjusted using advanced control algorithms. .
