This project is co-funded by the EEA Grants and the state budget of the Slovak Republic from the EEA Scholarship Programme Slovakia.
Grant scheme: Program EHP Slovakia – Mobility projects among universities – EEA/EHP-SK06-II-01
Project ID: SK06-II-01-004
Duration: 2.6.2015 - 30.9.2016
The aim of the project is to support international mobility of students, PhD students, and staff members of four participating faculties of STU in Bratislava with partners from NTNU Trondheim and Universität Liechtenstein. It will initiate academic cooperation between the University of Liechtenstein and STU Bratislava in construction, architecture, and space planning, focusing on the use of alternative energy sources in operation of buildings, including computer-aided simulations of energy needs and internal environment, and spatial planning of rural settlements as well. The project also contributes to further strengthening of already existing cooperation between NTNU Trondheim and faculties of STU in Bratislava in the field of advanced methods of automatic control and to progress of inter-faculty cooperation at STU in Bratislava.
Aims of the project for FCHPT STU
The project continues in preceding cooperation of three faculties STU (FCFT, FME, and FEEIT) with NTNU Trondheim in the field of automatic control realised within the framework of the project NIL-I-007-d that resulted in international impact (e.g. citations of resulting study materials and proceedings). This already existing cooperation within mobility project will be further expanded with focus on advanced methods of automatic control and their transition to educational process and to preparation of graduates in all three study stages for industrial praxis.
Overall, the mobility process will contribute to training of graduates with outstanding knowledge and abilities needed for work in international teams and for increased competitiveness of our education, research, development, and industry in the global framework.
I learnt basics of MPT Toolbox. I got familiarized with properties of polyhedron i.e. the construction of polyhedron with help of hyperplane (H-), Vertex (V-) representation and lower and upper bounds. I was able to work with polyhedron with equality and inequality constraints. I came to know about checking of Empty set, bounded and dimensional properties of a polyhedron.
I also learnt about designing and construction of a MPC Controller and Explicit MPC Controller. I was able to construct MPC Controller for a given LTI system with specific state and input constraints and state and input penalty functions. Explicit MPC was developed with the help of MPT Toolbox. I learnt about plotting and accessing partitions of Explicit MPC and I was successful in evaluation of a control law for such MPC.
I implemented different algorithms mentioned in Predictive Control for Linear and Hybrid Systems, F. Borrelli, A. Bemporad, M. Morari, for finding the region of current state for explicit MPC. Sequential search and maximum value algorithms were implemented along with the algorithm with descriptor function and their efficincies were measured by noting down the time elapsed during computations.
Outcomes of the stay:
The stay was focused on modeling and simulation of the CO2 removal process using membrane contactors. A model was developed to describe the CO2 removal process where two membrane contactors are used first to absorb carbon dioxide from the gas mixture and then to desorb it. The work consisted of literature review, modeling of membrane contactor for absorption process, modeling of two membrane contactors with absorption and desorption processes to remove carbon dioxide from the gas mixture, and testing and determination of the performance using simulations. A manuscript of a joint paper for the SSKI 2016 international conference was prepared. The model developed in this project will be subject to further work where the process will be optimized in order to achieve a better performance with maximum amount of CO2 being purified.
During the stay I also attented weekly meetings and seminars with the research group members, who gave me their support and also useful feedback for my work.
