    There are many techniques for phase-angle measurement. One technique is to use the least squares method (LSM). However, this method involves huge computations, especially when the number of samples is large. This paper presents an efficient systolic array system to speed up the LSM computation in a parallel and pipeline manner. The computation time, the speedup of the system and the delay of the p...

  • Weighted minimax design of fir QMF banks: Results and comparisons

    Publication Year: 1996, Page(s):61 - 66
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2441 KB)

    An iterative method proposed by Chen and Lee, with certain modifications based on the weighted least squares (WLS) updating scheme proposed by Sunder and Ramachandran, is applied to the design of FIR quadrature mirror-image filter (QMF) banks. The method is used to design QMF banks having equiripple reconstruction error with analysis and synthesis filters having equiripple or least squares stop-ba... View full abstract»

    In this paper, the recent development of a computer-aided partial discharge (PD) acoustic location system is briefly introduced. The paper presents the characteristics of this system with emphasis on the acoustic locating technique and interference countermeasures. Signal recognition, ascertainment of time delay and the location algorithms are discussed. A novel method for identifying multiple PD ... View full abstract»

  • An adaptive sliding-mode approach for force/motion control of manipulators under holonomic constraints

    Publication Year: 1996, Page(s):73 - 80
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1375 KB)

    This paper deals with the sliding-mode position/force control of constrained-manipulator systems, in which the constraints are supposed to be holonomic. An adaptive version of the controller is used for an on-line estimation of the unknown parameters. Because of this, no a priori knowledge of the bounds of unknown parameters is required. The algorithm guarantees asymptotic stability of the global ... View full abstract»

  • Power-system small-signal stability and maximum loadability

    Publication Year: 1996, Page(s):81 - 85
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2907 KB)

    This paper presents an efficient method for power-system maximum loadability assessment considering small-signal stability. Conventional methods are based on accurate load-flow solutions and calculation of all the system eigenvalues. The proposed method uses appropriate equivalents to reduce the computation time of the load-flow solution and also applies a special approach to find only the worst-d... View full abstract»
