  2. 1. On Observer-Based Control of Nonlinear Systems

    Author : Anders Robertsson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Observers; Output feedback; Separation principle; The Positive Real lemma; Kalman filter; Backstepping; Robotics; Automation; Chained form systems; reglerteknik; robotteknik; Automatiska system; control engineering; Lyapunov stability; Nonlinear systems; State estimation;

    Abstract : Filtering and reconstruction of signals play a fundamental role in modern signal processing, telecommunications, and control theory and are used in numerous applications. The feedback principle is an important concept in control theory. READ MORE

  4. 2. Hybrid observers for systems with intrinsic pulse-modulated feedback

    Author : Diana Yamalova; Alexander Medvedev; Xiaoming Hu; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid systems; impulsive systems; biomedical systems; Goodwin s oscillator; observers; time-delay; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : Dynamical processes resulting from the interaction of continuous and discrete dynamics are often encountered in living organisms. Time evolutions of such processes constitute continuous variables that are subject to instant changes at discrete points of time. READ MORE

  7. 5. Nonlinear observers with applications in the steel industry

    Author : Andreas Johansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Abstract : Access to measurements is a necessity in most technical applications, in order to detect faults, monitor performance, or exercise control. In some cases, however, installing measurement equipment is very expensive or even impossible. In such a case, estimates can be produced instead. READ MORE
