  • CCA - Recursive Model free control of variable speed wind turbine systems
    2012 IEEE International Conference on Control Applications, 2012
    Co-Authors: Haoping Wang, Nicolai Christov, A. Pintea, P. Borne, D. Popescu
    Abstract:

    The paper deals with the Recursive Model free control of horizontal variable speed wind turbines, which makes possible to obtain a compromise between the wind energy limitation, the rotor speed reference tracking and the decreasing of solicitations induced in the mechanical structure of the turbine. The wind turbine system dynamics is described by a multi-input multi-output nonlinear mathematical Model. A Recursive controller is proposed which uses only the measurement of the system output and does not require identification of turbine parameters. The effectiveness and the robustness of the new controller are analyzed by numerical simulation.

  • Modelling and Composed Recursive Model Free Control for the Anaerobic Digestion Process
    Advances in Intelligent Systems and Computing, 2020
    Co-Authors: Haoping Wang, Boyko Kalchev, Yang Tian, Ivan Simeonov, Nicolai Christov
    Abstract:

    This paper presents a Modelling and new composite Recursive Model free controller for trajectory tracking and disturbance compensation for the Anaerobic Digestion Process of cattle dung. The used Model is on the basis of a fifth-order continuous anaerobic digestion Model. And the proposed controller comprises a Recursive Model free controller based stabilization component and a time delay control based compensation component with Recursive calculation structure which does not require any knowledge of the Model parameters. Computer simulation examples illustrate the performance and robustness of the proposed approach.

  • Recursive Model free controller: Application to friction compensation and trajectory tracking
    International Journal of Control Automation and Systems, 2011
    Co-Authors: Haoping Wang, Yang Tian, C. Vasseur, V. Koncar, Nicolai Christov
    Abstract:

    In this paper friction compensation and trajectory tracking scheme is proposed for an X-Y robot using a Recursive Model Free Controller (RMFC). This controller is based on the theory of piecewise continuous systems which are a particular class of hybrid systems with autonomous switchings and controlled impulses. RMFC uses only the robot position measurements and does not require knowledge of electromechanical system parameters. The proposed control scheme is validated on a real time X-Y robot system.

  • Recursive Model Free Controller for trajectory tracking of MIMO nonlinear systems
    18th Mediterranean Conference on Control and Automation MED'10, 2010
    Co-Authors: Haoping Wang, C. Vasseur, V. Koncar, Nicolai Christov
    Abstract:

    This paper deals with a new Recursive Model Free Controller for trajectory tracking of MIMO nonlinear systems whose structure is simple and dose not depend on any physical Model. The proposed controller is based on the theory of a particular class of hybrid systems, called Piecewise Continuous Systems, which are characterized by autonomous switchings and controlled impulses. The effectiveness and robustness of the proposed controller is experimented on a three tank system.

  • Friction compensation of an X-Y robot using a Recursive Model Free Controller
    2010 IEEE International Conference on Industrial Technology, 2010
    Co-Authors: Haoping Wang, C. Vasseur, V. Koncar
    Abstract:

    In this paper, a friction compensation scheme for an X-Y robot's Model linearization via a Recursive Model Free Controller (RMFC) is proposed. In this scheme, the RMFC uses only the robot's position measurement for feedback and doesn't require knowledge of electromechanical system's parameters, such as parameters in the friction Model, rotor inertia, etc. The effectiveness and robustness of the proposed method is experimented on real time X-Y robot system.

  • refinement of software architectures by Recursive Model transformations
    Product Focused Software Process Improvement, 2006
    Co-Authors: Ricardo J Machado, Joao M Fernandes, Paula Monteiro, Helena Rodrigues
    Abstract:

    The main aim of this paper is to present how to refine software logical architectures by application of a Recursive Model-based transformation approach called 4SRS (four step rule set). It is essentially based on the mapping of UML use case diagrams into UML object diagrams. The technique is based on a sequence of steps that are inscribed in a tabular representation that is used to derive the software architecture for a focused part of the global system.
