  2. 1. Minimum-time sliding mode control of robot manipulators

    Author : Boyko Iliev; Ivan Kalaykov; Krzysztof Kozlowski; Örebro universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; minimum-time sliding mode control; sliding mode control; maximum-slope sliding lines; Takagi-Sugeno fuzzy systems; robot manipulators; reglerteknik; Automatic control; Reglerteknik; Reglerteknik; Automatic Control;

    Abstract : Robot manipulators have a complex and highly nonlinear dynamics, accompanied with a high degree of uncertainty. These properties make them difficult for time-optimal control. The theory of sliding mode control can provide methods, able to cope with the uncertainty and nonlinearity in the system. READ MORE

  4. 2. Underactuated mechanical systems : Contributions to trajectory planning, analysis, and control

    Author : Pedro La Hera; Anton Shiriaev; Ambarish Goswami; Umeå universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Underactuated mechanical systems; mechanical systems with impacts; trajectory planning; periodic trajectories; orbital stabilization; walking robots; virtual holonomic constraints; transverse linearization; Automatic control; Reglerteknik; Automatic Control; reglerteknik;

    Abstract : Nature and its variety of motion forms have inspired new robot designs with inherentunderactuated dynamics. The fundamental characteristic of these controlled mechanicalsystems, called underactuated, is to have the number of actuators less than the number ofdegrees of freedom. READ MORE

  5. 3. Complexity Issues, Validation and Input Design for Control in System Identification

    Author : Märta Barenthin Syberg; Bo Wahlberg; Håkan Hjalmarsson; Lennart Ljung; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic control; Reglerteknik;

    Abstract : System identification is about constructing and validating modelsfrom measured data. When designing system identificationexperiments in control applications, there are many aspects toconsider. One important aspect is the choice of model structure.Another crucial issue is the design of input signals. READ MORE

  6. 4. Aspects of proactive traffic engineering in IP networks

    Author : Anders Gunnar; Mikael Johansson; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURAL SCIENCES; NATURVETENSKAP; Automatic control; Reglerteknik;

    Abstract : To deliver a reliable communication service over the Internet it is essential for the network operator to manage the traffic situation in the network. The traffic situation is controlled by the routing function which determines what path traffic follows from source to destination.

  7. 5. Compensating for Unreliable Communication Links in Networked Control Systems

    Author : Erik Henriksson; Karl Henrik Johansson; Henrik Sandberg; Bruno Sinopoli; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networked control; packet loss compensation; unreliable communication; control over wirless networks; Automatic control; Reglerteknik;

    Abstract : Control systems utilizing wireless sensor and actuator networks can be severely affectedby the properties of the communication links. Radio fading and interferencemay cause communication losses and outages in situations when the radio environmentis noisy and low transmission power is desirable. READ MORE
