  1. 1. Real-Time Control Systems with Delays

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

    Author : Johan Nilsson; [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

  2. 2. Flexible Scheduling Methods and Tools for Real-Time Control Systems

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

    Author : Dan Henriksson; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control; Simulation Tools; Delay Compensation; Feedback Scheduling; Real-Time Control;

    Abstract : This thesis deals with flexibility in the design of real-time control systems. By dynamic resource scheduling it is possible to achieve on-line adaptability and increased control performance under resource constraints. The approach requires simulation tools for control and real-time systems co-design. READ MORE

  3. 3. Continuous-Time Delta-Sigma Modulators for Wireless Communication

    University dissertation from Department of Electrical and Information Technology, Lund University

    Author : Mattias Andersson; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; return-to-zero; A D converter; loop delay; delta-sigma; ADC; CMOS; STF; continuous-time; sigma; delta; filtering; CT; RZ;

    Abstract : The ever increasing data rates in wireless communication require analog to digital converters (ADCs) with greater requirements on speed and accuracy, while being power efficient to prolong battery life. This dissertation contains an introduction to the field and five papers that focus on the continuous-time (CT) Delta-Sigma modulator (DSM) as ADC. READ MORE

  4. 4. Distributed Control of Electric Drive Systems via Ethernet

    University dissertation from Stockholm : KTH

    Author : Lilantha Samaranayake; Chandur Sadarangani; Alexander Medvedev; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adaptive sampling scheme; control delay; delay compensation; distributed control systems; Ethernet; Ethernet ready sensor actuator module; sampling period; TECHNOLOGY Electrical engineering; electronics and photonics Electrical engineering; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektroteknik;

    Abstract : This thesis is on adapting standard Switched Ethernet for distributed control applications in electric drive systems. The critical issue of Ethernet here is to provide services to real-time applications. READ MORE

  5. 5. Transient Air to Fuel Ratio Response in a Fuel Injected S.I Engine

    University dissertation from Stockholm : KTH

    Author : Göran Almkvist; [1995]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; dynamic; A F; model; transient; air to fuel; response; time constant; film; behavior; lambda; time-delay; fuel; mass; deposit factor;

    Abstract : Future emission standards make it necessary to focus on the conditions under which engine emissions are produced, especially before the catalyst light off. During practical driving conditions, such as those represented by the FTP 75 test cycle, the engine is operated very much under transient conditions regarding load and speed. READ MORE
