  • digital simulation and hardware implementation of a simple scheme for direct torque control of induction motor
    Energy Conversion and Management, 2008
    Co-Authors: Dinkar Prasad, B P Panigrahi, S Sengupta
    Abstract:

    A simple scheme that allows fast control of induction motor torque has been presented. It is different from the conventional direct torque control (DTC) scheme in the sense that it does not use the popular DTC switching table. Also, it does not require use of any online fast Computing Device like a microprocessor, personal computer (PC) or digital signal processor (DSP). The proposed scheme uses only commonly used discrete hardware components for its implementation. The experimental results obtained from the hardware realization of the proposed scheme are found to be in close agreement with the simulation results.

  • a simple hardware realization of switching table based direct torque control of induction motor
    Electric Power Systems Research, 2007
    Co-Authors: B P Panigrahi, Dinkar Prasad, S Sengupta
    Abstract:

    A simple hardware realization of direct torque control (DTC) scheme for fast control of induction motor torque has been presented. The proposed hardware scheme mimics the conventional switching table based DTC scheme and does not require use of any online fast Computing Device like microprocessor, PC or DSP. The controller uses only commonly used discrete hardware components. The experimental results of the proposed hardware implementation have been presented and supported with simulation results. Another alternate hardware scheme without using the switching table has also been proposed and the experimental results of both the schemes have been compared and found to be in agreement with each other.

  • polynomial time algorithms for prime factorization and discrete logarithms on a quantum computer
    Siam Review, 1999
    Co-Authors: Peter W Shor
    Abstract:

    A digital computer is generally believed to be an efficient universal Computing Device; that is, it is believed to be able to simulate any physical Computing Device with an increase in computation time by at most a polynomial factor. This may not be true when quantum mechanics is taken into consideration. This paper considers factoring integers and finding discrete logarithms, two problems that are generally thought to be hard on classical computers and that have been used as the basis of several proposed cryptosystems. Efficient randomized algorithms are given for these two problems on a hypothetical quantum computer. These algorithms take a number of steps polynomial in the input size, for example, the number of digits of the integer to be factored.
