This paper presents a resonance suppression method that reduces current oscillation incurred by the LCL-filtered grid-connected converter’s discontinuous PWM (DPWM). First, the cause of LCL resonance is analyzed with an aspect of frequency and time

The accuracy of positron emission tomography (PET) imaging is hampered by the partial volume effect (PVE), which causes image blurring and sampling. The PVE produces spillover phenomena, making PET analysis difficult. Generally, the PVE values vary b

This paper analyzes the effect of discretization in the frequency-adaptive flux observer (FAO). Although FAO has structural simplicity and ease of implementation, the discrete-time FAO has phase and gain errors in fundamental flux estimation. As a re

In this paper, a maximum online torque per ampere (MTPA) control is proposed for torque control of interior permanent magnet synchronous motors (IPMSMs). First, torque and MTPA equations are derived based on flux variables, where the influence of mag
