  2. 2. On the Mean Square Error of Transfer Function Estimates with Applications to Control

    Författare :Svante Gunnarsson; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mean square error; Transfer function; Estimation; Applications;

    Sammanfattning : In this report we study the mean square error of transfer function estimates obtained by identification. The model quality is related to the use of models in regulator design, and the properties of affecting the bias part of the mean square error, both in fixed parameter control and adaptive control.

  3. 3. QoS Control of Real-Time Data Services under Uncertain Workload

    Författare :Mehdi Amirijoo; Jörgen Hansson; Sang Son; Svante Gunnarsson; Joseph Hellerstein; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; real-time system; database; feedback control; Computer science; Datavetenskap;

    Sammanfattning : Real-time systems comprise computers that must generate correct results in a timely manner. This involves a wide spectrum of computing systems found in our everyday life ranging from computers in rockets to our mobile phones. The criticality of producing timely results defines the different types of realtime systems. LÄS MER

  4. 4. Modeling and Diagnosis of Friction and Wear in Industrial Robots

    Författare :André Carvalho Bittencourt; Svante Gunnarsson; Mikael Norrlöf; Andrew Starr; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : High availability and low operational costs are critical for industrial systems. While industrial equipments are designed to endure several years of uninterrupted operation, their behavior and performance will eventually deteriorate over time. LÄS MER

  5. 5. On Modeling and Diagnosis of Friction and Wear in Industrial Robots

    Författare :André Carvalho Bittencourt; Svante Gunnarsson; Mattias Nyberg; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Industrial robots are designed to endure several years of uninterrupted operation and therefore are very reliable. However, no amount of design effort can prevent deterioration over time, and equipments will eventually fail. Its impacts can, nevertheless, be considerably reduced if good maintenance/service practices are performed. LÄS MER
