The Process Matters: Cyber Security in Industrial Control Systems The Process Matters: Cyber Security in Industrial Control Systems

An industrial control system (ICS) is a computer system that controls industrial processes such as power plants, water and gas distribution, food production, etc. Since cyber-attacks on an ICS may have devastating consequences on human lives and safety in general, the security of ICS is important. In this context, the most valuable asset is the process that is under the control of the ICS. As a...

Toward Industrial Process Control Applications of the Backstepping

This paper addresses practical aspects of the application of the backstepping method to the control of industrial processes. The limitations are emphased and solutions are proposed. The steady-state performances of the backstepping-based controllers are enhanced via the introduction of an integral action in the controller. In presence of non-zero mean perturbations, this modification guarantees...

An Expert-Aided Implementation Interface for Industrial Process Control Systems

We present the design and implementation of a new expert-system “front end” or Design Advisor for Implementing Systems (dais) for use in conjunction with a commercial digital control system environment, e.g., the Elsag Bailey infi 90 System. The objective of dais is to make it substantially easier for applications engineers to make effective use of the broad spectrum of capabilities of this and...

Intelligent Decoupling Control System of Complex Industrial Process and Application

A new decoupling control structure is presented for complex industrial processes, which consists of a feedback controller, a decoupling compensator and a feedforward compensator for unmodeled dynamics. Using this structure, an intelligent decoupling control system is established which realizes an adaptive decoupling control strategy for industrial processes with integrated complexities by using...
