In this paper, at first, a 24/16 three-phase switched reluctance motor is designed, then the rotor poles shape tips corrected for reduction ripple of single-phase torque waveform. By doing this, the single-phase torque waveform has a flat surface and consequently, the single-phase torque ripple is reduced. Also, due to the commutation between the machine phases, the torque drops during this tim...
In this paper, model predictive control (MPC) is proposed for single-phase electric springs (ESs) with the help of existing δ control, which realized by controlling instantaneous phase angle predefined sinusoidal reference a certain controller. System modeling analyzed first to get differential forms state variables. The discrete-time space obtained through first-order approximation. Critical l...
i read with interest the papers written by peyghambari et al (2008) and niknafs et al nd et al et al et al et al et al et al et al (1994) did not observe any advantage in the pregnancy rates when adding estrogen+progesterone at luteal phase in patients undergoing ivf (6). in conclusion, the mechanism of luteal phase support in assisted reproduction is complex and a controver...
