  1. 1. Optimal simultaneous excitation for identification of multivariable systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gunnar Sigurðsson; [2023]
    Keywords : System identification; Simultaneous excitation; Experiment design; Model Predictive Control MPC ; Optimization; Multivariable systems; Systemidentifiering; Simultan excitation; Experimentdesign; Modell Predictive Control MPC ; Optimering; Multivariabla system;

    Abstract : Having a accurate model of a system is essential for many applications today, especially those related to advanced process control. When executing a project often a lot of time is spent performing experiments on the real system to estimate a model. READ MORE

  3. 2. Ensuring high-quality production during commissioning and ramp-up : A case study at Northvolt

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Henrik Eklund; Jacob Engström; [2021]
    Keywords : Quality assurance; commissioning; production ramp-up; measurement system analysis; statistical process control; capability analysis;

    Abstract : Rechargeable lithium-ion batteries (LIBs) have generated a shift in the automotive industry towards electric vehicles (EVs) instead of vehicles powered by fossil fuels. As a result, the demand for LIBs is only expected to grow in the future due to an increased demand for passenger EVs. READ MORE

  4. 3. Implementation of improved fat standardization using statistical process control

    University essay from Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Author : Lovisa Bjenning; [2019]
    Keywords : Milk; Whole milk; Semi-skimmed milk; Fat content; Statistical process control; MilkoScan FT2;

    Abstract : The aim of this project was to apply statistical process control (SPC) and measure the variation of fat content in milk in order to improve the standardization, so that the fat content does not change more than 0.03 percentage units from target. Recommendations of how to adjust the standardization should also be developed. READ MORE

  5. 4. Non-parametric Statistical Process Control : Evaluation and Implementation of Methods for Statistical Process Control at GE Healthcare, Umeå

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Daniel Lanhede; [2015]
    Keywords : Statistical process control SPC ; non-parametric; distribution-free; control charts; Phase I analysis; Phase II analysis; Recursive segmentation and permutation RS P ; change-point model CPM ;

    Abstract : Statistical process control (SPC) is a toolbox to detect changes in the output of a process distribution. It can serve as a valuable resource to maintain high quality in a manufacturing process. READ MORE

  6. 5. A practical approach to detection of plant model mismatch for MPC

    University essay from Reglerteknik

    Author : Rickard Carlsson; [2010]
    Keywords : Model Predictive Control; Model Plant Mismatch; Error Detection; Partial Correlation;

    Abstract : The number of MPC installations in industry is growing as a reaction to demands of increased efficiency. An MPC controller uses an internal plant model to run real-time predictive optimization of future inputs. If a discrepancy between the internal plant model and the plant exists, control performance will be affected. READ MORE
