  1. 1. Controlling the Roll Responses of PCTC's

    Författare :Carl-Johan Söder; Jakob Kuttenkeuler; Dominic Hudson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PCTC; parametric roll; roll response; roll damping; rudder control; roll mitigation; racking;

    Sammanfattning : Modern Panamax Pure Car and Truck Carriers (PCTC) have become more vulnerable to critical roll responses as built in margins have been traded against increased transport efficiency. The research presented in this licentiate thesis aims at enhancing the predictability and control of these critical roll responses. LÄS MER

  3. 2. Local and Piecewise Affine Approaches to System Identification

    Författare :Jakob Roll; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Identification of nonlinear systems is a multifaceted research area, with many diverse approaches and methods. This thesis considers two different approaches: (nonparametric) local modelling, and identification of piecewise affine systems. LÄS MER

  4. 3. Optimal Decisions with Limited Information

    Författare :Ather Gattami; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; systems; numerical analysis; Computer science; Convex Optimization; Graph Theory; Team Decision Theory; Game Theory; control; Datalogi; numerisk analys; system; kontroll; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : This thesis considers static and dynamic team decision problems in both stochastic and deterministic settings. The team problem is a cooperative game, where a number of players make up a team that tries to optimize a given cost induced by the uncertainty of nature. LÄS MER

  5. 4. Robust Verification and Identification of Piecewise Affine Systems

    Författare :Jakob Roll; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piecewise affine systems; Verification; Robustness; Identification; Mixed-integer programming;

    Sammanfattning : iecewise affine systems constitute an important subclass of hybrid systems, and consist of several affine dynamic subsystems, between which switchings occur at different occasions. As for hybrid systems in general, there has been a growing interest for piecewise affine systems in recent years, and they occur in many application areas. LÄS MER

  7. 5. Vehicle Dynamics Control for Rollover Prevention

    Författare :Brad Schofield; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rollover Prevention; Control Allocation; Nonlinear Control; Convex Optimization; Vehicle Dynamics;

    Sammanfattning : Vehicle rollover accidents are a particularly dangerous form of road accident. Existing vehicle dynamics controllers primarily deal with yaw stability, and are of limited use for dealing with problems of roll instability. LÄS MER
