  1. 36. Gradient Methods for Large-Scale and Distributed Linear Quadratic Control

    Author : Karl Mårtensson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Large-Scale Control; Distributed Control; Linear Quadratic Gaussian Control; Gradient method; Controller Synthesis;

    Abstract : This thesis considers methods for synthesis of linear quadratic controllers for large-scale, interconnected systems. Conventional methods that solve the linear quadratic control problem are only applicable to systems with moderate size, due to the rapid increase in both computational time and memory requirements as the system size increases.

  2. 37. Flexible Embedded Control Systems : Design and Implementation

    Author : Johan Eker; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automation; Feedback scheduling; Quality of service; Linear quadratic control; Toolbox; Simulation; Rapid prototyping; Programming language; Scheduling; Embedded systems; Real-time system; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : Embedded control system design is a complex and error prone task, and there is a great need for better development tools. Today most real-time control systems are static systems, designed in an ad-hoc fashion. A more interactive way of working would give shorter development times, reduced costs for testing, and safer, more robust systems. READ MORE

  3. 38. Iterative Road Grade Estimation for Heavy Duty Vehicle Control

    Author : Per Sahlholm; Karl Henrik Johansson; Jonas Sjöberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road grade; estimation; heavy duty vehicle; Kalman filter; automatic control; Automatic control; Reglerteknik;

    Abstract : This thesis presents a new method for iterative road grade estimation based on sensors that are commonplace in modern heavy duty vehicles. Estimates from multiple passes of the same road segment are merged together to form a road grade map, that is improved each time the vehicle revisits an already traveled route. READ MORE

  4. 39. Identification, Diagnosis, and Control of a Flexible Robot Arm

    Author : Måns Östring; Svante Gunnarsson; Mikael Norrlöf; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Identification; Robot; Flexible; Diagnosis; Control; LQG; Recursive;

    Abstract : The most important factors in manufacturing are quality, cost, and productivity. The trend is towards lighter robots with increased mechanical flexibilities, and therefore there is a need to include the flexibilities in the robot models to obtain good performance of the robot.

  5. 40. Optimal Control and Model Reduction of Nonlinear DAE Models

    Author : Johan Sjöberg; Torkel Glad; Xiaoming Hu; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DAE Models; Optimal Control; Model Reduction; Automatic control; Reglerteknik;

    Abstract : In this thesis, different topics for models that consist of both differential and algebraic equations are studied. The interest in such models, denoted DAE models, have increased substantially during the last years. READ MORE
