  3. 2. Modelling and control of rotary crane systems

    Författare :Thomas Gustafsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : This thesis is devoted to the modelling and control of rotary crane systems. The goal is to design a control system that assists the operator to move a cargo without oscillations and to correctly align the cargo at the final position. LÄS MER

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

    Författare :Jonas Öhr; Mikael Sternad; Anders Ahlén; Tore Hägglund; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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.
