A method for the process model identification in a closed-loop is presented and a design approach of IMC-PID in terms of robust stability and robust performance is developed. The algorithm of IMC-PID is implemented in DCS via module configuration. It promotes robust stability and the robust performance of PID. Its control action is very quick and the system is maintenance-free. As its application a software for the process model identification in the closed-loop and the design of IMC-PID is developed. Applying this system to an atmospheric and vacuum distillation unit,the result is perfect.
