In this thesis, a Reinforcement Learning (RL) method called Sarsa is used to dynamically tune a PI-controller for a Continuous Stirred Tank Heater (CSTH) experimental setup. The proposed approach uses an approximate model to train the RL agent in the simulation environment before implementation...

In this thesis, we propose a computationally efficient economic model predictive control (EMPC) design which is based on a well-known methodology --- the separation of the control and prediction horizon. The extension of the prediction horizon of EMPC is realized by employing an auxiliary control...

Wastewater treatment plays an important role in the sustainable development of our society. A wastewater treatment plant (WWTP) is typically a large-scale nonlin- ear process composed of several interconnected operating units. To meet the strict environmental regulations, to ensure the operation...

Bitumen extracted from oil sands has been a major source of wealth for Canada, but it comes at a high price because the Clark hot water process generates large volumes of tailings which must be stored in ponds that threaten the environment. These tailing ponds must be treated to meet the land...

Bitumen froth is produced from mined oil sands using the water-based extraction process. The froth is very viscous and contains roughly 60% bitumen, 30% water, and 10% fine solids (by mass). The mixture of water, fine solids, and dissolved ions in the froth is usually called carrier fluid. The...
