  1. 1. Linear Parameter-Varying Systems - an approach to gain scheduling

    Author : Fredrik Bruzelius; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; linear parameter-varying systems; linear matrix inequalities; h-inf control; gain scheduling; nonlinear L2 l2 control;

    Abstract : In recent years the interest for gain scheduling methods has increased. Gain scheduling is a collection of methods that try to tackle the challenging problem of nonlinear control in a divide and conquer manner. The use of local linear system theory to obtain a non-local controller is the fundament of the gain scheduling methods. READ MORE

  2. 2. Methods for robust gain scheduling

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Anders Helmersson; Linköpings universitet.; Linköpings universitet.; [1995]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Regulatorer används i många tillämpningar för att förbättra prestanda ochegenskaper hos fordon och farkoster av olika slag, t ex flygplan och raketer.Beroende på olika faktorer, som hastighet och höjd, kan dynamiken ochuppträdandet av dessa farkoster variera. READ MORE

  3. 3. Understanding Task Parallelism Providing insight into scheduling, memory, and performance for CPUs and Graphics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Germán Ceballos; Uppsala universitet.; Uppsala universitet.; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Task-based programming; Task Scheduling; Analytical Cache Model; Scheduling; Runtime Systems; Computer Graphics rendering ; Computer Science; Datavetenskap;

    Abstract : Maximizing the performance of computer systems while making them more energy efficient is vital for future developments in engineering, medicine, entertainment, etc. However, the increasing complexity of software, hardware, and their interactions makes this task difficult. READ MORE

  4. 4. Gain-Scheduled Controller Design

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Adrian Ilka; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Guaranteed cost control; Gain-scheduled control; Bellman-Lyapunov function; Lyapunov theory of stability; Robust control; Input output constraints; LPV system;

    Abstract : This thesis is devoted to controller synthesis, i.e. to finding a systematic procedure to determine the optimal (sub-optimal) controller parameters which guarantees the closed-loop stability and guaranteed cost for uncertain nonlinear systems with considering input/output constraints, all this without on-line optimization.

  5. 5. Cross-layer Aspects in OFMDA Systems Feedback, Scheduling and Beamforming

    University dissertation from Stockholm : KTH

    Author : Patrick Svedman; KTH.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Information technology Telecommunication; TEKNIKVETENSKAP Informationsteknik Telekommunikation;

    Abstract : This thesis mainly studies the downlink of a wireless multiuser system, where the transmitter has limited knowledge about the communication channels of the users. Key techniques to improve the performance of such systems are, for instance, multiple antennas, multiuser diversity and orthogonal frequency-division multiple access (OFDMA). READ MORE
