  1. 1. Toward Adaptation of Data Enabled Predictive Control for Nonlinear Systems

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hashem Ghasemi; [2022]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Extraction of Loudspeaker- and room impulse responses under overlapping conditions

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Felix Gustafsson; [2022]
    Nyckelord :Signal processing; Optimization; Acoustics; Dereverberation; Sparse deconvolution; Multipath propagation;

    Sammanfattning : A loudspeaker is often considered to be a Linear Time Invariant (LTI) system, which can be completely categorized by its impulse response. What sets loudspeakers apart from other LTI-systems is the acoustical aspect including echoes, which makes it a lot harder to take accurate noise free measurements compared to other LTI-systems such as a simple RC circuit.

  4. 3. Reference Tracking with Adversarial Adaptive Output- Feedback Model Predictive Control

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Linda Bui; [2021]
    Nyckelord :Model Predictive Control; Adversarial Multi-Armed Bandits; Kalman Filter; Output-Feedback; Adaptive Control ; Modell Prediktiv Reglering; Kontradiktoriska Flerarmade Banditer; Kalman Filter; Output-Feedback; Adaptiv Reglering;

    Sammanfattning : Model Predictive Control (MPC) is a control strategy based on optimization that handles system constraints explicitly, making it a popular feedback control method in real industrial processes. However, designing this control policy is an expensive operation since an explicit model of the process is required when re-tuning the controller. LÄS MER

  5. 4. Convex Optimization Methods for System Identification

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Dino Dautbegovic; [2014]
    Nyckelord :Mathematical Optimization; Convex Optimization; Least-Squares; LTI-System; System Identification; Inverse System;

    Sammanfattning : The extensive use of a least-squares problem formulation in many fields is partly motivated by the existence of an analytic solution formula which makes the theory comprehensible and readily applicable, but also easily embedded in computer-aided design or analysis tools. While the mathematics behind convex optimization has been studied for about a century, several recent researches have stimulated a new interest in the topic. LÄS MER

  7. 5. Linear Time Periodic Analysis of Dc-Dc converter

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Simone Del Favero; [2006]
    Nyckelord :HTM; Harmonic Transfer Matrix; HTF; Harmonic Transfer Function; LTP; Linear Time Periodic Systems; PWM; Dc-Dc converter; Pulse Width Modulator; subharmonics; chaos; subharmonic estimation; Technology and Engineering;

    Sammanfattning : Aim of this thesis is to analyze Dc-Dc converters by using the techniques of Linear Periodic Time varying (LTP) systems to estimate the amount of subharmonics injected in the load. Dc-Dc converters are used to transform a Dc input to a Dc output of different voltage. In this thesis we study in particular the so called "switch mode" converters. LÄS MER
