This paper presents an improved stator flux estimation technique based on a voltage model with some form of low-pass (LP) filtering. In voltage-model-based stator flux estimation, an LP filter is normally used instead of a pure integrator to avoid integration drift problem due to dc offset, noise, or measurement error present in the back electromotive(More)
On the basis of one personal case, the various clinicopathological features of primary malignant fibrous histiocytoma of the lung are summed up. This tumor, which has a nonspecific radiological appearance, most often appears as a large peripheral pulmonary opacity, for which the prognosis is guarded and the positive diagnosis based on surgical exeresis or(More)
This paper presents a new switching method for cascaded multilevel inverter (CMI). The new method uses multiple non-sinusoidal signals as the modulating signal. The main advantage of using nonsinusoidal modulating signal is that it provides higher fundamental component but at the cost of having a numbers of low-order harmonics in its unfiltered output(More)
