  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]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Timing jitter; Stochastic parameters; Stochastic control; Real-time systems; Linear quadratic control; Jump linear systems; Distributed computer control systems; Clock synchronization; Delay compensation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : Control loops that are closed over a communication network get more and more common. A problem with such systems is that the transfer delays will be varying with different characteristics depending on the network hardware and software. READ MORE

    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
