  2. 1. Anti-windup and Control of Systems with Multiple Input Saturations : Tools, Solutions and Case Studies

    Author : Jonas Öhr; Mikael Sternad; Anders Ahlén; Tore Hägglund; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Anti-windup compensator; saturating actuator; amplitude limiter; rate limiter; path anti-windup; double integrator; time-optimal control; container crane; spreader; hydraulic cylinder; Reglerteknik; Automatic control; Reglerteknik;

    Abstract : Control of linear systems with saturating actuators are considered and anti-windup compensators for multiple-input multiple-output systems, and robust, almost time-optimal controllers for double integrators with input amplitude saturations, are proposed.Windup effects are defined and anti-windup compensators aiming at minimizing the windup effects are proposed.

  4. 2. Control of Multi-Agent Systems with Applications to Distributed Frequency Control Power Systems

    Author : Martin Andreasson; Karl H. Johansson; Wei Ren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Multi-agent systems are interconnected control systems with many application domains. The first part of this thesis considers nonlinear multi-agent systems, where the control input can be decoupled into a product of a nonlinear gain function depending only on the agent's own state, and a nonlinear interaction function depending on the relative states of the agent's neighbors.

  5. 3. Resource-Constrained Multi-Agent Control Systems: Dynamic Event-triggering, Input Saturation, and Connectivity Preservation

    Author : Xinlei Yi; Karl H. Johansson; Lihua Xie; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Consensus; Connectivity; Dynamic event-triggered control; Formation control; Input saturation; Multi-agent systems; Self-triggered control; Electrical Engineering; Elektro- och systemteknik;

    Abstract : 978-91-7729-579-2A multi-agent system consists of multiple agents cooperating to achieve a common objective through local interactions. An important problem is how to reduce the amount of information exchanged, since agents in practice only have limited energy and communication resources. READ MORE

  6. 4. On performance limitations of large-scale networks with distributed feedback control

    Author : Emma Tegling; Henrik Sandberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; microgrids; platooning; vehicular formation; multi-agent systems; H2 norms; fundamental limitations; consensus; Distributed control; large-scale networks; oscillator networks; power networks; power system dynamics; system performance; spatially invariant systems; Electrical Engineering; Elektro- och systemteknik;

    Abstract : We address the question of performance of large-scale networks with distributed feedback control. We consider networked dynamical systems with single and double integrator dynamics, subject to distributed disturbances. We focus on two types of problems. First, we consider problems modeled over regular lattice structures. READ MORE

  7. 5. Minimum-time sliding mode control of robot manipulators

    Author : Boyko Iliev; Ivan Kalaykov; Krzysztof Kozlowski; Örebro universitet; []
    Keywords : 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
