Industrial Process Measurement and Control Systems (IPMCS) are used in most of the industrial sectors to achieve production improvement, process optimisation and time and cost reduction. Integration, reuse, flexibility and optimisation are demanded to adapt to a rapidly changing and competitive market. There is also a growing requirement that all software tools that support the different phases...

År 2004 har varit det första året av Fas IV. Under året har fördjupningen och utvidgningen av samarbetet fortsatt mellan de deltagande företagen och forskargrupperna vid LiTH (Linköpings Tekniska Högskola) och har resulterat i industriellt relevanta forskningsresultat. Huvudaktiviteten inom ISIS är forskningsprojekten. Projekten har valts ut för att vara av central betydelse för företagen. Att ...

In this article the applications of differential flatness to some industrial systems are presented. Computational methods of obtaining the flat output and the straight forward method of constructing the corresponding control law are given. Some theoretical and industrial systems are used as illustration including the third order synchronous machine model and the one degree of freedom magnetic l...

Estimating the execution time of software components is often mandatory when evaluating the nonfunctional properties of software-intensive systems. This particularly holds for real-time embedded systems, e.g., in the context of industrial automation. In practice it is however very hard to obtain reliable execution time estimates which are accurate, but not overly pessimistic with respect to the...

Industrial Control Systems (ICS) are an integral part of the industrial infrastructure providing for the national good. These systems include Distributed Control Systems (DCS) Supervisory Control and Data Acquisition systems (SCADA), Programmable Logic Controllers (PLC), and devices such as remote telemetry units (RTU), smart meters, and intelligent field instruments including remotely programm...

The secure and reliable operation of industrial control systems is becoming more and more challenging due to the increasing size, complexity, and heterogeneity of such systems. A constant change of requirements and responsibilities results in an increased frequency of configuration and topological changes, which renders a manual verification of system security infeasible. Thus, there is a need ...

With the development of industrial automation technology, the limitation of traditional cable control network has become increasingly prominent. Consequently, establishing a reliable data transmission network becomes a critical demand in industry. Increasingly, companies developing monitoring and control applications in industrial and commercial building environments are looking to wireless tec...

The paper present the possibility of automatic control of the biological wastewater treatment station with applications in Romanian Chemical Companies. In this paper are developed a mathematical model for biological aeration basins and two automatic control systems (conventional control structure using threepositional controllers or PLC and advanced control structure using state estimators) for...

Conducting security tests such as vulnerability discovery within Industrial Control Systems (ICS) help reduce their vulnerability to cyber attacks. Unfortunately, the extreme availability requirements on ICS in operation make it difficult to conduct security tests in practice. For this reason, researchers and practitioners turn to testbeds that mimic real ICS. This study surveys ICS testbeds th...

In this paper, we summarize advantages of using agent technology in the design and operation of industrial control systems. To support appropriate responses to dynamically generated events, we divided the agent operation into two main levels: planning and real-time control. A higher-level software agent covers the planning phase and low-level distributed control agent provides the real-time con...
