  1. 1. Fixed-Feedback SISO Adaptive Control

    Author : Magnus Nilsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Two-Degrees-of-Freedom Control; Feedforward Control; Adaptive Control;

    Abstract : Adaptive control is an attractive method to solve control problemssince the tedious task of identifying process behavior to find asuitable design for the controller is taken care of by the adaptivecontroller itself. It may be difficult, however, to guaranteerobustness (in the sense of desired disturbance attenuation andstability margins) for traditional adaptive schemes since theircorresponding loop gain is time varying.

  2. 2. Compliance Control of Robot Manipulator for Safe Physical Human Robot Interaction

    Author : Muhammad Rehan Ahmed; Ivan Kalaykov; Kystof Kozlowksi; Örebro universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physical human robot interaction; collision safety; variable stiffness actuators; compliance control; TECHNOLOGY; TEKNIKVETENSKAP; Automatic control; Reglerteknik; Reglerteknik; Automatic Control;

    Abstract : Inspiration from biological systems suggests that robots should demonstrate same level of capabilities that are embedded in biological systems in performing safe and successful interaction with the humans. The major challenge in physical human robot interaction tasks in anthropic environment is the safe sharing of robot work space such that robot will not cause harm or injury to the human under any operating condition.

  3. 3. 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

  4. 4. Planning and Control of Uncertain Cooperative Mobile Manipulator-Endowed Systems under Temporal Logic Tasks

    Author : Christos Verginis; Dimos Dimarogonas; Magnus Egerstedt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-agent systems; cooperative manipulation; formation control; temporal logic; motion planning; adaptive control; funnel control; navigation; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Control and planning of multi-agent systems is an active and increasingly studied topic of research, with many practical applications such as rescue missions, security, surveillance, and transportation. This thesis addresses the planning and control of multi-agent systems under temporal logic tasks. READ MORE

  5. 5. Coordination, Consensus and Communication in Multi-robot Control Systems

    Author : Alberto Speranzon; Karl Henrik Johansson; George J. Pappas; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-robot Coordination; Intelligent Control; Control under Communication Constraints; Automatic control; Reglerteknik;

    Abstract : Analysis, design and implementation of cooperative control strategies for multi-robot systems under communication constraints is the topic of this thesis. Motivated by a rapidly growing number of applications with networked robots and other vehicles, fundamental limits on the achievable collaborative behavior are studied for large teams of autonomous agents.
