  1. 1. Data Driven Model Identification for Remote Electrical Tilt Systems

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Raphaël Ashruf; [2023]
    Keywords : ;

    Abstract : This thesis explores the use of supervised machine learning for modelling the dynamics of Remote Electrical Tilt (RET) telecom systems. Three methodologies, including linear regressionfor linear dynamics models, Gaussian Process (GP) regression, and Recurrent Neural Networks (RNN) with Gated Recurrent Units (GRU) are proposed.

  3. 2. Grey-box Modeling of Hydropower Plants for Improved Frequency Regulation : Evaluation of Double-Regulated Hydropower Turbines for Fulfillment of the New FCR-requirements

    University essay from Uppsala universitet/Elektricitetslära

    Author : Karolina Engström; Rebecca Waldenfjord; [2023]
    Keywords : Double-regulated hydroturbines; Grey-box modeling; FCR-requriements; Frequency contaminent reserve; Hydropower modeling; Dynamic stability; Dynamic performance;

    Abstract : Over the last decades, the frequency on the Nordic electrical power grid has deteriorated. Therefore, new stricter requirements are developed for the hydropower delivering regulating active power on the Frequency Containment Reserve market (FCR). READ MORE

  4. 3. Toward Adaptation of Data Enabled Predictive Control for Nonlinear Systems

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

    Author : Hashem Ghasemi; [2022]
    Keywords : DeePC; Data Driven Control; Nonlinear System; Non-holonomic Ground Robot; Double Integrator Model; Inverted Pendulum.; DeePC; Datadriven Kontroll; Icke-linjärt System; Icke-holonomisk Markrobot; Dubbelintegratormodell; Inverterad Pendel;

    Abstract : With the development of technology and availability of data, it is sometimes easier to learn the control policies directly from the data, rather than modeling a plant and designing a controller. Modeling a plant is not always possible due to the complexity of the plant. READ MORE

  5. 4. System Identification of continuous-time systems with quantized output data using indirect inference

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

    Author : Frida Persson; [2021]
    Keywords : System Identification; Indirect Inference; Continuous-Time Systems; Identification of Non- Linear systems; Hammerstein system.; Systemidentifiering; Tidskontinuerliga system; Icke-linjära system; Hammerstein system.;

    Abstract : Continuous-time system identification is an important subject with applications within many fields. Many physical processes are continuous in time. Therefore, when identifying a continuous-time model, we can use our insight into the system to decide the system structure and have a direct interpretation of the parameters. READ MORE

  6. 5. Neural Network Based Model Predictive Control of Turbulent Gas-Solid Corner Flow

    University essay from Uppsala universitet/Signaler och system

    Author : Simon Wredh; [2020]
    Keywords : computational fluid dynamics; machine learning; system identification; control theory; multi-phase flow; gas-solid flow; rans; lagrangian particle tracking; neural network; model predictive control; bio-aerosol;

    Abstract : Over the past decades, attention has been brought to the importance of indoor air quality and the serious threat of bio-aerosol contamination towards human health. A novel idea to transport hazardous particles away from sensitive areas is to automatically control bio-aerosol concentrations, by utilising airflows from ventilation systems. READ MORE
