1. 1. Noise and Saturation Properties of Fiber Optical

   Författare :Per Kylemark; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear fiber optics; four-wave mixing; single-pumped; regeneration; saturation; dual-pumped; noise figure; parametric amplification;

   Sammanfattning : Fiber Optical Parametric Amplifiers (FOPAs) are based on a highly efficient Four-wave Mixing process in highly nonlinearfibers and have gained a lot of interest since it was shown that ahigh gain can be obtained. They are multi-functional devices thatare not only limited to amplifying signals, but their wide range ofapplicability also include wavelength conversion, pulse-generation,optical sampling and also regeneration at very high bit-rates.

3. 2. Active Vibration Control of Multibody Systems : Application to Automotive Design

   Författare :Claes Olsson; Alexander Medvedev; Stephen Elliott; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Vibration Control; Vibration Isolation; Feedback Control; Adaptive Filtering; Saturation; Limit Cycles; Multi Body Systems; Modelling; Simulation; Non-linearity; Gain Scheduling; Structure Flexibility; Automatic control; Reglerteknik;

   Sammanfattning : Active vibration control to reduce vibrations and structure borne noise is considered using a powerful multi-disciplinary virtual design environment which enables control system design to be considered as an integral part of the overall vehicle design. The main application studied is active automotive engine vibration isolation where, first, the potential of large frequency band multi-input multi-output H2 feedback control is considered. LÄS MER

4. 3. Distributed control of interconnected systems and its application in traffic control

   Författare :Azita Dabiri; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linear Matrix Inequality; Distributed control; Traffic flow modelling and control; Input saturation;

   Sammanfattning : Over the past few decades, the need for mobility and road transportation has been significantly increased over the world. This turned as a dilemma in many metropolitan areas as traffic congestion costs energy and takes time of all individuals who live in big cities. LÄS MER

5. 4. On the control of systems with input saturation or periodic disturbances

   Författare :Kirthi Sarachchandra Walgama; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Sammanfattning : This thesis deals with two important problems in control theory and practice. The first problem is the windup problem in controllers where there exist non-linearities between the controller output and the process input. LÄS MER

7. 5. Resource-Constrained Multi-Agent Control Systems: Dynamic Event-triggering, Input Saturation, and Connectivity Preservation

   Författare :Xinlei Yi; Karl H. Johansson; Lihua Xie; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Consensus; Connectivity; Dynamic event-triggered control; Formation control; Input saturation; Multi-agent systems; Self-triggered control; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : 978-91-7729-579-2A multi-agent system consists of multiple agents cooperating to achieve a common objective through local interactions. An important problem is how to reduce the amount of information exchanged, since agents in practice only have limited energy and communication resources. LÄS MER
