1. Management control and strategy : a case study of pharmaceutical drug development
Abstract : How are formal management controls designed and used in research & development (R&D)? The purpose of this study is to explain how such systems are designed and used in formulating and implementing strategies in a pharmaceutical product development organisation. The study uses a contingency approach to investigate how the control system is adjusted to the business strategy of the firm. READ MORE

2. Applications of Information Inequalities to Linear Systems : Adaptive Control and Security
Abstract : This thesis considers the application of information inequalities, Cramér-Rao type bounds, based on Fisher information, to linear systems. These tools are used to study the trade-offs between learning and performance in two application areas: adaptive control and control systems security. READ MORE

3. Robust Control of an Induction Motor Drive
Abstract : This thesis considers robust control of an induction motor drive, consisting of an input filter, a voltage source inverter and one or several induction motors in parallel. The motor torque is here controlled by using the method Indirect Self Control (ISC), and power oscillations between the inverter and the input filter are damped by means of a stabilization controller in an outer feedback loop.

4. Fault detection in lambda-tuned control loops
Abstract : Poorly operating control loops cause loss in productivity in almost every industry worldwide. Therefore performance monitoring has been an active area of research for the past decades. In this work, a newly developed fault detection method is applied to the monitoring of lambda-tuned control loops. READ MORE

5. Computational Methods for Optimal Control of Hybrid Systems
Abstract : This thesis aims to find algorithms for optimal control of hybrid systems and explore them in sufficient detail to be able to implement the ideas in computational tools. By hybrid systems is meant systems with interacting continuous and discrete dynamics. Code for computations has been developed in parallel to the theory. READ MORE
