  1. 1. Synthesis of a Model-based Tire Slip Controller

    Author : Stefan Solyom; Lunds universitet.; Lund University.; [2002]
    Keywords : synthesis; LMI; hybrid; piecewise linear; ABS; PID; TEKNIKVETENSKAP; TECHNOLOGY;

    Abstract : The Anti-lock Braking System (ABS) is an important component of a complex steering system for the modern car. In the latest generation of brake-by-wire systems, the performance requirements on the ABS have changed. The controllers have to be able to maintain a specified tire slip for each wheel during braking. READ MORE

  2. 2. PID control of TITO systems

    Author : Pontus Nordfeldt; Lunds universitet.; Lund University.; [2005]
    Keywords : PID Control; Decoupling; Linear Systems; Process Control; Multi-variable Control; TEKNIKVETENSKAP; TECHNOLOGY;

    Abstract : This thesis treats controller design and tuning for systems with two input signals and two output signals in the process industry. Two design methods that can be combined to form a core in an algorithm for automatic design and tuning for the considered systems are presented. READ MORE

  3. 3. PID Controllers Design and Evaluationn

    University dissertation from Chalmers University of Technology

    Abstract : PID control has been the most widely spread form of feedback in industry for at least five or six decades. It has very old roots, but prior to the 1930s the development was driven by instrument companies, plant designers and plant operators. Today the interest among academics is large and increasing.

    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. 5. Closed-Loop Combustion Control of a Multi Cylinder HCCI Engine using Variable Compression Ratio and Fast Thermal Management

    University dissertation from Division of Combustion Engines/Department of Heat and Power Engineering/Lund Institute of Technology

    Author : Göran Haraldsson; Lunds universitet.; Lund University.; [2005]
    Keywords : Motorer; CR; framdrivningssystem; Motors and propulsion systems; Teknik; Technological sciences; Closed-Loop Combustion Control; CLCC; Multi cylinder; HCCI; Black box; System identification; State feedback; PID; LQG; Fast Thermal Management; FTM; VCR Variable Compression Ratio; TEKNIKVETENSKAP; TECHNOLOGY;

    Abstract : The current Spark Ignited (SI) engine equipped with three-way catalyst offers low emissions, but has low efficiency at part load, which results in unnecessarily high CO2 emissions. The Compression Ignited (CI) engines have higher efficiency and hence lower CO2 emissions, but suffer from higher Nitrogen Oxide (NOx) and Particulate Matter (PM) emissions, and no three-way catalyst can be used.
