An advanced process control algorithm, namely, model PID or IMC-PID based on internal model control (IMC), is developed. They can be implemented on DCS. The original PID parameters need to be modified into IMC-PID parameters, which are calculated by the process models. It significantly increases the control speed and the accuracy, and also has good tracking ability for the set-point control, combining with improved robustness for disturbance and model's time-varying character. It had successfully applied to refinery and petro-chemical plants, and has potential wide applications on other plants also.
