  4. 3. Contributions to motion planning and orbital stabilization : case studies: Furuta pendulum swing up, inertia wheel oscillations and biped robot walking

    Författare :Pedro Xavier Miranda La Hera; Anton Shiriaev; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Under-actuated Systems; Orbital Exponential Stability; Motion Planning; Virtual Constraints; Walking robots; Automatic control; Reglerteknik;

    Sammanfattning : Generating and stabilizing periodic motions in nonlinear systems is a challenging task. In the control system community this topic is also known as limit cycle control. In recent years a framework known as Virtual Holonomic Constraints (VHC) has been developed as one of the solutions to this problem. LÄS MER

  5. 4. Principles for planning and analyzing motions of underactuated mechanical systems and redundant manipulators

    Författare :Uwe Mettin; Anton Shiriaev; Alin Albu-Schäffer; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motion Planning; Underactuated Mechanical Systems; Redundant Manipulators; Virtual Holonomic Constraints; Orbital Stabilization; Human Movement; Walking Robots; Hydraulic Manipulators; Electrical engineering; Elektroteknik; Automatic Control; reglerteknik;

    Sammanfattning : Motion planning and control synthesis are challenging problems for underactuated mechanical systems due to the presence of passive (non-actuated) degrees of freedom. For those systems that are additionally not feedback linearizable and with unstable internal dynamics there are no generic methods for planning trajectories and their feedback stabilization. LÄS MER

  7. 5. Underactuated mechanical systems : Contributions to trajectory planning, analysis, and control

    Författare :Pedro La Hera; Anton Shiriaev; Ambarish Goswami; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
