  1. 1. Piecewise Linear Control Systems

    University dissertation from Department of Automatic Control, Lund Institute of Technology (LTH)

    Author : Mikael Johansson; Lunds universitet.; Lund University.; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piecewise quadratic functions; Linear matrix inequalities; Convex optimization; Optimal control; Performance analysis; Piecewise linear Lyapunov functions; Piecewise quadratic Lyapunov functions; Quadratic stability; Lyapunov stability; Piecewise linear systems; Nonlinear systems; Fuzzy systems; Hybrid systems.; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : This thesis treats analysis and design of piecewise linear control systems. Piecewise linear systems capture many of the most common nonlinearities in engineering systems, and they can also be used for approximation of other nonlinear systems. READ MORE

  2. 2. Real-Time Control Systems with Delays

    University dissertation from Department of Automatic Control, Lund Institute of Technology (LTH)

    Author : Johan Nilsson; Lunds universitet.; Lund University.; [1998]

    Abstract : Popular Abstract in Swedish Inbyggda styrsystem finns idag överallt omkring oss. Moderna bilar, cd-spelare och mobiltelefoner är bara några exempel på produkter som inte skulle fungera utan datorbaserade reglersystem. READ MORE

  5. 5. Linear Quadratic Gaussian Controllers for Feedforward Active Noise Control : Pushing Performance and Moving Towards Adaptive Control

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Annea Barkefors; Uppsala universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active noise control; ANC; LQG; feedforward control; sound field control; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : Active noise control is a research area focused on using destructive interference of sound fields to attenuate undesired noise. Methods for active noise control are best suited for low frequency noise, as the complexity of the problem grows rapidly with frequency. READ MORE
