    An application of an automatic control strategy to a solar plant for material treatment has been shown. Since these kinds of plants are manually operated by skilled operators, the development of an automatic control strategy aimed at achieving adequate results throughout the wide range of operating conditions, under which these plants operate, represents an important improvement towards facilitati...

    A model based friction compensation scheme using a novel dynamical friction model was implemented on an industrial Schilling Titan II hydraulic robot. Off-line estimation of parameters was carried out, using the results of two kinds of experiments. These experiments were done independently at each joint. A nonlinear PI type controller was used in the inner torque loop to improve its performance. T... View full abstract»

    Modeling, control, and gas leakage detection in the coal injection process are discussed. It is shown that by use of model-based methods, the flow and pressure of the coal injection vessel are reliably controlled. With the new control law, the coal mass flow can be used as a control parameter for the blast furnace. High injection rates can be used and more coke substituted, This is expected to yie...

  • LPV techniques for control of an inverted pendulum

    Publication Year: 1999, Page(s):44 - 54

    The authors present a comprehensive application of linear fractional transformation and polytopic control techniques to the control of an arm-driven inverted pendulum, The particular interest of this application lies in the fact that all ingredients of the design problem have to be taken into account; from the specifications up to the constraints inherent to real-world implementations. In this con... View full abstract»

    In this paper, an integrated system for the design, development, and testing of guidance, navigation, and control algorithms for unmanned air vehicles was presented. Extensive use was made of commercial off-the-shelf hardware. This kept costs relatively low and made the system easily scaleable. Sophisticated autocode tools allowed a two man team to write, test, and maintain thousands of lines of e... View full abstract»

    This article summarizes the results of an experimental comparison of nonlinear control algorithms on a DC-DC power converter of the boost type. It compares five algorithms, including the linear design, with respect to their ease of design and their closed-loop performance. For all these algorithms local asymptotic stability of the desired equilibrium is ensured. The motivation of the present study... View full abstract»

    This paper gives an overview on the topic of control education on the Web. Accompanied by a Web page, the material is partly tutorial, enabling readers to step in at their current levels and move forward in their Web usage. For those readers who have not yet made use of the Web in their courses, we will demonstrate models of Web sites for consideration to suggest what can be done, and offer introd...

    2 case studies; the Shchipanov Affair of 1940-41, and the work of Andronov in the late 1940s. The author attempts to identify and elucidate some of the socio-political complexities that lie behind theoretical developments in control engineering in the former Soviet Union. The ideological background to scientific research was a crucial element in the 1930s and 1940s: it served to severely hinder ea... View full abstract»
