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

    Author : Pedro La Hera; Anton Shiriaev; Ambarish Goswami; Umeå universitet; []
    Keywords : 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

  4. 7. On Compositional Supervisor Synthesis for Discrete Event Systems

    Author : Sahar Mohajerani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; abstraction; supervisory control theory.; synthesis; Finite-state automata;

    Abstract : Over the past decades, human dependability on technical devices has rapidlyincreased. Many activities of such devices can be described by sequences ofevents, where the occurrence of an event causes the system to go from onestate to another. This is elegantly modeled by automata.

  5. 8. Funnel-Based Control for Coupled Spatiotemporal Specifications

    Author : Farhad Mehdifar; Dimos V. Dimarogonas; Charalampos P. Bechlioulis; Bayu Jayawardhana; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Funnel-Based Control; Prescribed Performance Control; Uncertain Nonlinear Systems; Time-Varying Output Constraints; Coupled Spatiotemporal Constraints; Formation Control; Multi-Agent Systems; Trattbaserad kontroll; föreskriven prestandakontroll; osäkra icke-linjära system; tidsvarierande utgångsbegränsningar; kopplade rumsliga begränsningar; formationskontroll; multiagentsystem; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In the past decade, the integration of spatiotemporal constraints into control systems has emerged as a crucial necessity, driven by the demand for enhanced performance, guaranteed safety, and the execution of complex tasks. Spatiotemporal constraints involve criteria that are dependent on both space and time, which can be represented by time-varying constraints in nonlinear control systems. READ MORE

  6. 9. Compositional Approaches in Supervisory Control with Application to Automatic Generation of Robot Interlocking Policies

    Author : Hugo Flordal; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nonblocking; finite state automata; verification; controllability; Discrete event systems; model reduction; synthesis; interlocking; supervisory control;

    Abstract : The work presented in this thesis concerns verification and synthesis in the Ramadge and Wonham supervisory control framework. Supervisory control constitutes a formal framework for the design of supervisors for discrete event systems. READ MORE

  7. 10. Incremental and Hierarchical Deadlock-Free Control of Discrete Event Systems with Variables: A Symbolic and Inductive Approach

    Author : Mohammad Reza Shoaei; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete event systems; IC3; large-scale systems; model checking; incremental control; supervisory control; hierarchical control; maximal permissiveness;

    Abstract : Today's industry trend towards agile product development cycles and the ambition to shorten the time-to-market, represents an extremely competitive marketplace. This has driven the industry to use very complex and highly flexible manufacturing systems. READ MORE
