  2. 21. Towards Active Car Body Suspension in Railway Vehicles

    Author : Jessica Fagerlund; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decoupling; Model reduction; Active suspension; MIMO systems; LQ control;

    Abstract : Today, most railway suspension systems are passive. The most wide-spread exception isactive car body tilt systems, which are mounted in some high-speed trains. Replacingsome of the passive suspension components with active could reduce the weight and costof the vehicle. READ MORE

  4. 22. PID Control, Design, Extension, Application

    Author : Helene Panagopoulos; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; PID control. Design. Optimization. Load disturbance rejection. Measurement noise filtering. Set point response. Robustness. Sensitivity. H-infinity control. Undamped process modes. Active control. Allpass and bandpass filter. Evaluation. Steam generator.

    Abstract : This thesis considers the design of PID controllers, the extensions of these controllers to improve their performance, and the applications of these design methods to industrial processes. New tuning methods for PI and PID controllers have been presented. These methods uses a model of the process to be controlled, given as a transfer function. READ MORE

  5. 23. Dryer Section Control in Paper Machines During Web Breaks

    Author : Jenny Ekvall; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dryer Section; Web breaks; Paper machine; steam pressure control; Physical modeling; Automatic control; Reglerteknik; Dryer section; paper machine; physical modeling; steam pressure control; web breaks;

    Abstract : Web breaks in the dryer section of a paper machine cause loss of production and quality problems. After a web break, the steam pressure in the cylinders must be reduced to avoid overheating. READ MORE

  6. 24. On Supervisor Synthesis via Active Automata Learning

    Author : Ashfaq Hussain Farooqui; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supervisory control theory; Finite-state machines; Active learning; Model learning; Automata learning; Discrete-event systems;

    Abstract : Our society's reliance on computer-controlled systems is rapidly growing. Such systems are found in various devices, ranging from simple light switches to safety-critical systems like autonomous vehicles. In the context of safety-critical systems, safety and correctness are of utmost importance. READ MORE

  7. 25. Planning and Control of Cooperative Multi-Agent Manipulator-Endowed Systems

    Author : Christos Verginis; Dimos V. Dimarogonas; Pedro Lima; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-agent systems; Temporal logics; Cooperative manipulation; Motion planning; Control; Navigation; Action planning; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Multi-agent planning and control is an active and increasingly studied topic of research, with many practical applications, such as rescue missions, security, surveillance, and transportation. More specifically, cases that involve complex manipulator-endowed systems  deserve extra attention due to potential complex cooperative manipulation tasks and their interaction with the environment.
