  • A sampled-data level control of nonlinear coupled-tanks

    Publication Year: 2012, Page(s):3 - 8
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (170 KB) | HTML iconHTML

    The object of this work is to highlight, on a physical coupled tanks system, the performances of a digital design of a continuous-time passivity based controller. The design considers the sampled-data model of the plant and provides better results compared to the emulations of given continuous-time controllers. A two-state continuous-time non-linear model is used to design the digital controller. ... View full abstract»

    In this paper a three-phase shunt active power filter with sliding mode control is presented. The reference current is determined in a simple manner by multiplying each phase voltage with a factor depending on the power absorbed by the nonlinear load. Sliding mode is analyzed on each phase considering the interactions between the three phases. The system was simulated and implemented. The experime... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (143 KB) | HTML iconHTML

    This paper considers the design of observers for periodic Takagi-Sugeno fuzzy models. The observer employed is also a periodic one. To develop the design conditions, a switching Lyapunov function defined at the time instants when the subsystems switch is used. Using the developed conditions we are able to design observers for TS models where the local models or even the subsystems are unstable. Th... View full abstract»

    The Detector Control System (DCS) of the COMPASS experiment at CERN is presented. The experiment has a high level of complexity and flexibility and a long time of operation, that constitute a challenge for its full monitorisation and control. A strategy to use a limited number of standardised, cost-effective, industrial solutions of hardware and software was pursued. When such solutions were not a... View full abstract»

    In coal power plants from Romania, there is a major interest for the implementation of digital systems for monitoring and control, replacing the conventional control systems for power, frequency and voltage. Therefore it is necessary to develop mathematical models capable to accurately describe both dynamic and stationary behaviour of the coal burning units, in order to be able to implement digita...

    Along last decades, the power system protection relay has experienced many important changes, from purely electromechanical type to fully numerical relays based on microprocessors. In the transformer protection area, similar changes can be seen. The numerical protection systems have control functions such as on load tap changer control function in combination with protection system so that a prote... View full abstract»

    Achieving of the desired performance for manufacturing systems is one very important goal when solving of planning and scheduling tasks. Corresponding management of orders and invested assets demands for multi-level and multi-objective optimization. Software systems of Enterprise Resource Planning (ERP) and Manufacturing Execution System (MES) applications used presently in practice are based on d... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (595 KB) | HTML iconHTML

    One of the most important problems when considering the design of multi agent manufacturing systems based on SOA paradigms is the lack of a simulation environment that would allow independent development and testing of the services and business processes of the manufacturing hardware. The paper presents the design and implementation of a complete simulation environment for service oriented multi a... View full abstract»

    In this paper absolute stability for a longitudinal low order ADMIRE model with rate limited actuator is investigated using a frequency Popov-type criterion. The analysis is performed in the frame of the Lurie problem with rate limited actuator representing the nonlinear part and the linearized low order ADMIRE system expressing the linear part. The closed loop transfer function has one simple pol... View full abstract»

    Hydrogen economy relies on hydrogen production. One method for hydrogen production is the water electrolysis in solid polymer electrolyte electrolyzers using electrical energy from renewable energy sources such a solar energy. The hydrogen produced with such system is of very high purity (more than 99.9%) suitable for later usage in fuel cells systems. This paper proposes a specific design for the... View full abstract»

    This paper presents a new rotor flux and rotor speed observer of induction motor. The new observer is based on an adaptive mechanism. The design of the new observer is done using the notion of Lyapunov stability. The observer is designed to be used within a speed sensorless direct rotor field oriented control of induction motors.
