1. Perturbation-based Control of Industrial Fed-batch Bioprocesses
University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund UniversityAbstract : The topic of this thesis is bioprocess control, more specifically control of industrial-scale microbial fed-batch bioprocesses. Its focus is therefore on methods which are easy to implement in an industrial setting, which gives certain limitations on sensors, actuators and control systems. READ MORE

2. Probing Control of Glucose Feeding in Escherichia coli Cultivations
University dissertation from Department of Automatic Control, Lund Institute of Technology (LTH)Abstract : Production of many proteins can today be made using genetically modified organisms. One of the most frequently used host organisms is the bacterium Escherichia coli. A difficulty encountered in cultivations of E. coli is the accumulation of the metabolic by-product acetate which inhibits cell growth and production of a desired protein. READ MORE

3. Extremum-seeking Control of Industrial-scale Fermentation Processes
University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund UniversityAbstract : The work presented here is based on two papers, both pertaining to perturbation-based control strategies in industrial fed-batch fermentation processes. The first paper describes a new control strategy for avoiding overflow metabolism in the exponential growth phase of a fermentation, based on analysis of the frequency spectrum of the dissolved oxygen measurement following a periodic perturbation in the feed rate.

4. Structure-Exploiting Numerical Algorithms for Optimal Control
University dissertation from Linköping : Linköping University Electronic PressAbstract : Numerical algorithms for efficiently solving optimal control problems are important for commonly used advanced control strategies, such as model predictive control (MPC), but can also be useful for advanced estimation techniques, such as moving horizon estimation (MHE). In MPC, the control input is computed by solving a constrained finite-time optimal control (CFTOC) problem on-line, and in MHE the estimated states are obtained by solving an optimization problem that often can be formulated as a CFTOC problem.
