16. Design of Robust PID Controllers with Constrained Control Signal Activity
Abstract : This thesis presents a new method for design of PI and PID controllers with the level of control signal activity taken into consideration. The main reason why the D-part is often disabled in industrial control loops is because it leads to control signal sensitivity of measurement noise. READ MORE

17. Quality Control of a Newsprint TMP Refining Process based on Refining Zone Temperature Measurements
Abstract : The ultimate goal of this study was to examine the possibility of using temperature measurements for control purposes in a TMP refining process. The study was carried out in a commercial refiner line at Holmen Paper’s Hallsta Mill, were the primary stage refiner was equipped with temperature sensors. READ MORE

19. Modelling, analysis and experimentation of a simple feedback scheme for error correction control
Abstract : Data networks are an important part in an increasing number of applications with real-time and reliability requirements. To meet these demands a variety of approaches have been proposed. Forward error correction, which adds redundancy to the communicated data, is one of them. READ MORE
