1. Relay Feedback and Multivariable Control
Abstract : This doctoral thesis treats three issues in control engineering related to relay feedback and multivariable control systems. Linear systems with relay feedback is the first topic. Such systems are shown to exhibit several interesting behaviors. READ MORE

2. Ammonium Feedback Control in Wastewater Treatment Plants
Abstract : The aeration process is often the single largest consumer of electricity in a wastewater treatment plant. Aeration in biological reactors provides microorganisms with oxygen which is required to convert ammonium to nitrate. Ammonium is toxic for aqueous ecosystems and contributes to eutrophication.

3. Interaction Analysis in Multivariable Control Systems : Applications to Bioreactors for Nitrogen Removal
Abstract : Many control systems of practical importance are multivariable. In such systems, each manipulated variable (input signal) may affect several controlled variables (output signals) causing interaction between the input/output loops. READ MORE

4. Control and Estimation of Automotive Powertrains with Backlash
Abstract : In automotive powertrains, backlash causes problems with vehicle driveability, specifically at so called tip-in and tip-out maneuvers. These maneuvers may trigger phenomena known in the automotive industry as shunt and shuffle, which are partially caused by the backlash. READ MORE

5. On Modeling and Control of Flexible Manipulators
Abstract : Industrial robot manipulators are general-purpose machines used for industrial automation in order to increase productivity, flexibility, and quality. Other reasons for using industrial robots are cost saving, and elimination of heavy and health-hazardous work. READ MORE
