2. 1. Batch Control and Diagnosis

   Author : Rasmus Olsson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multivariate Statistical Analysis; State and Parameter Estimation; Dynamic Models; Fault Detection; Exception Handling; Recipe; S88; Batch Control; PCA; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : Batch processes are becoming more and more important in the chemical process industry, where they are used in the manufacture of specialty materials, which often are highly profitable. Some examples where batch processes are important are the manufacturing of pharmaceuticals, polymers, and semiconductors. READ MORE

4. 2. On Kinematic Modelling and Iterative Learning Control of Industrial Robots

   Author : Johanna Wallén; Mikael Norrlöf; Svante Gunnarsson; Geir Hovland; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial robots; kinematics; Maple; modelling; iterative learning control; experiments; Automatic control; Reglerteknik;

   Abstract : Good models of industrial robots are necessary in a variety of applications, such as mechanical design, performance simulation, control, diagnosis, supervision and offline programming. This motivates the need for good modelling tools. In the first part of this thesis the forward kinematic modelling of serial industrial robots is studied. READ MORE

5. 3. Automatic Synthesis of Sequential Control Schemes

   Author : Inger Klein; Lennart Ljung; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Of all hard- and software developed for industrial control purposes, the majority is devoted to sequential, or binary valued, control and only a minor part to classical linear control. Typically, the sequential parts of the controller are invoked during startup and shut-down to bring the system into its normal operating region and into some safe standby region, respectively.

6. 4. Exception Handling in Recipe-Based Batch Control

   Author : Rasmus Olsson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; S88; grafchart; exception handling; recipe; batch;

   Abstract : The focus of this thesis is exception handling in recipe-based batch control. Exception handling is a critical element for achieving long-term success in batch production. It is reported to constitute 40-60 percent of the batch control design and implementation effort. READ MORE

7. 5. Toward Secure and Reliable Networked Control Systems

   Author : André Teixeira; Henrik Sandberg; Karl H. Johansson; Kameshwar Poolla; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Security and reliability are essential properties in Networked Control Systems (NCS), which are increasingly relevant in several important applications such as he process industry and electric power networks. The trend towards using non-proprietary and pervasive communication and information technology (IT) systems, such as the Internet and wireless communications, may result in NCS being vulnerable to cyber attacks.
