Direct Torque Control is a control technique in AC drive systems to obtain high performance torque control. The conventional DTC drive contains a pair of hysteresis comparators. DTC drives utilizing hysteresis comparators suffer from high torque ripple and variable switching frequency. The most common solution to those problems is to use the space vectorâ€¦ (More)

Till recently dedicated hardware has been required to perform real-time MPEG-2 video encoding. However, with increase in clock frequency and the introduction of video-specific instruction sets, general-purpose processors and DSPs can now approximate the function and performance of single-function hardware. In this paper, a software-only MPEG-2(MP@ML) videoâ€¦ (More)

This paper proposes a novel Space Vector Pulse width modulation (SVPWM) for sensor less control of induction motor using model reference adaptive system (MRAS). The steady state ripples in the torque are present in the conventionally used MRAS sensor less control of induction motor which utilizes normally used voltage source inverters. Also performance ofâ€¦ (More)

A fast motion vector estimation algorithm for Field Motion Estimation having computational complexity independent of search range is presented for interlaced video encoding. The algorithm is based on spatial correlation of motion vectors and yields good tradeoff between motion estimation distortion and number of SAD computations. The speed up achieved byâ€¦ (More)

The basic direct torque control algorithm gives large ripples in torque, flux and current in steady state, which results in acoustical noise and incorrect speed estimations. The conventional SVPWM algorithm gives good performance for control of induction motor drive, but it produces more acoustical noise resulting in increased total harmonics distortion.â€¦ (More)
