  2. 21. Analysis and Design of Hybrid Control Systems

    Author : Jörgen Malmborg; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lyapunov theory; Mode switching; Multi-controllers; PID control; Simulation; Higher order sliding; Hybrid control; Sliding modes; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : Different aspects of hybrid control systems are treated: analysis, simulation, design and implementation. A systematic methodology using extended Lyapunov theory for design of hybrid systems is developed. The methodology is based on conventional control designs in separate regions together with a switching strategy. READ MORE

  4. 22. Look-ahead Control of Heavy Vehicles

    Author : Erik Hellström; Lars Nielsen; Jan Åslund; Lino Guzzella; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automotive control; dynamic programming; predictive control; fuel-optimal control; long haulage truck; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Automatic control; Reglerteknik;

    Abstract : Trucks are responsible for the major part of inland freight and so, they are a backbone of the modern economy but they are also a large consumer of energy. In this context, a dominating vehicle is a truck with heavy load on a long trip. READ MORE

  5. 23. The Core of Aerial Robotic Workers : Generalized Modeling, Estimation, and Control

    Author : Emil Fresk; George Nikolakopoulos; Thomas Gustafsson; Ming Cao; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerial robotics; generalized modeling; generalized estimation; generalized control; Reglerteknik; Control Engineering;

    Abstract : In this thesis we are going to explore what the operational core, both mathematically and algorithmically, of an Aerial Robotic Worker consists of, in order to estimate its egomotion and parameters, and adaptively control the aerial vehicle. Moreover, the aim of this thesis is to be a condensed reference for the corresponding areas of aerial robotics, in order to provide a stable and complete foundation on which one can continue research on.

  6. 24. Estimation and Control of Resonant Systems with Stochastic Disturbances

    Author : Peter Nauclér; Torsten Söderström; Anders Robertsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration control; stochastic control; stochastic systems; feedforward control; Wiener filtering; Kalman filtering; wave separation; unbalance estimation; nonlinear regression; Automatic control; Reglerteknik;

    Abstract : The presence of vibration is an important problem in many engineering applications. Various passive techniques have traditionally been used in order to reduce waves and vibrations, and their harmful effects. Passive techniques are, however, difficult to apply in the low frequency region. READ MORE

  7. 25. Quality-Driven Synthesis and Optimization of Embedded Control Systems

    Author : Soheil Samii; Petru Eles; Zebo Peng; Samarjit Chakraborty; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Embedded control; distributed embedded systems; distributed control; control quality; control performance; scheduling; optimization; adaptive system; multi-mode system; fault tolerance; self-triggered control; Computer science; Datavetenskap;

    Abstract : This thesis addresses several synthesis and optimization issues for embedded control systems. Examples of such systems are automotive and avionics systems in which physical processes are controlled by embedded computers through sensor and actuator interfaces. READ MORE
