This paper presents direct and independent torque control of induction motors using the technique called direct torque control (DTC), which is an on-off control scheme. Stator flux and the electromagnetic torque are directly controlled by applying the appropriate voltage vector from a look-up table. The simulation results for electro- magnetic torque, flux,(More)
The objective of the present study is to find out the optimum extraction conditions for extraction of polyphenols from red grapes using Box-Behnken design. Red grapes polyphenols were extracted using acid-ethanol solvent at various extraction temperature (40-60°C), extraction time (20-100 min) and different solid-liquid ratio (1:5-1:15 g:ml). The effect(More)
Abstract: In this paper, we consider the problem of dissipativity and passivity analysis for complex-valued discrete-time neural networks with time-varying delays. The neural network under consideration is subject to time-varying. Based on an appropriate Lyapunov–Krasovskii functional and by using the latest free-weighting matrix method, a sufficient(More)
The focus of this paper is the actual implementation of the algorithm onto FPGA hardware. A simple nonlinear median based high pass filter algorithm has been implemented using Xilinx ISE 12.2 targeted for FPGA — xc6slx4–3tqg144. The filter structure consists of a median filter followed by a high pass filter. The signal to be filtered is the(More)
This paper is concerned with the mixed $$H_\infty$$ H ∞ and dissipativity performance for Markovian jump neural networks with time delay in the leakage term and randomly occurring uncertainties. The randomly occurring uncertainties are assumed to be mutually uncorrelated Bernoulli-distributed white noise sequences. By introducing a triple-integrable term in(More)
In this paper, a novel approach is proposed for the design of low power CMOS band gap reference circuit. In the literature, an inversion technique is proposed to make the voltage reference to be independent of temperature by using parasitic bipolar transistors. In the above technique, this paper proposes the use of MOSFETs operating in sub threshold region(More)
