A model driven PID control system and its application to chemical processes

PID control systems are used as a basic control technology in contemporary industry. However, there are issues regarding control performances for some controlled processes, such as long dead-time processes and unstable processes. In order to improve the control performances of PID control systems, we proposed a new model driven PID control system, which is combined with the following control scheme; PD feedback, internal model control, set point filter and PV filter. In this paper, the model driven PID control system, its design method and application results for chemical processes are described.
