PID control systems are widely used as a basic control technology in the industrial control system today. However, tuning of PID control systems is not always easy, because of its simple control structure to wide classes of industrial control processes. In order to improve the issues, we developed a ModelDriven PID control system, named MD PID Control system, by extending the “model driven cont...

This paper presents a new control-loop configuration criterion for multivariable processes. Both the steady-state and transient information of the process transfer function are investigated. A new interaction measurement, relative normalized gain array, is proposed for evaluating control-loop interactions. Consequently, a new loop pairing criterion based on the relative normalized gain array is...

A multivariable laboratory process of four interconnected water tanks is considered for modeling and robust control. The objective of the current study is to design and implement a variety of control algorithms and present corresponding robust control analysis on a multivariable laboratory four tank process. The control methodologies considered are (i) decentralized PI control, (ii) “inner-oute...
