  1. 1. Stochastic Event-Based Control and Estimation

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Toivo Henningsson; Lunds universitet.; Lund University.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; event-based control; event-based estimation; sporadic control; stochastic control; stochastic hybrid systems; sum-of-squares methods; control over networks; quantized measurements;

    Abstract : Digital controllers are traditionally implemented using periodic sampling, computation, and actuation events. As more control systems are implemented to share limited network and CPU bandwidth with other tasks, it is becoming increasingly attractive to use some form of event-based control instead, where precious events are used only when needed.

  2. 2. Event-Based Control and Estimation with Stochastic Disturbances

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Toivo Henningsson; Lunds universitet.; Lund University.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; event-based control; stochastic control; event-based estimation; control over networks; quantized measurements; sporadic control; embedded control;

    Abstract : This thesis deals with event-based control and estimation strategies, motivated by certain bottlenecks in the control loop. Two kinds of implementation constraints are considered: closing one or several control loops over a data network, and sensors that report measurements only as intervals (e.g. with quantization).

  3. 3. 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

  4. 4. Estimation and Control of Resonant Systems with Stochastic Disturbances

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Peter Nauclér; Uppsala universitet.; Uppsala universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration control; stochastic control; stochastic systems; feedforward control; Wiener filtering; Kalman filtering; wave separation; unbalance estimation; nonlinear regression; TECHNOLOGY Information technology Automatic control; TEKNIKVETENSKAP Informationsteknik Reglerteknik;

    Abstract : The presence of vibration is an important problem in many engineering applications. Various passive techniques have traditionally been used in order to reduce waves and vibrations, and their harmful effects. Passive techniques are, however, difficult to apply in the low frequency region. READ MORE

  5. 5. Methods for Stochastic Optimal Control under State Constraints

    University dissertation from Chalmers University of Technology

    Author : Per Rutquist; Chalmers tekniska högskola.; Chalmers University of Technology.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimal control; Fokker-Planck-Kolmogorov equation; Hamilton-Jacobi-Bellmanequation; stochastic systems; control theory;

    Abstract : This thesis looks at a few different approaches to solving stochas-tic optimal control problems with state constraints. The motivatingproblem is optimal control of an energy buffer in a hybrid vehicle,although applications are abundant in a number of areas. READ MORE
