This paper presents a two-order A-type iterative learning control (ILC) scheme along time axis using a switching (SW) Q-filter to restrain periodic force ripples of permanent magnet linear synchronous motor (PMLSM). The purpose of employing the time-varying SW Q-filter is to utilize the enhanced robustness given by a low bandwidth filter, while taking advantage of the superior properties of a high...
This paper focuses on adaptive velocity compensation along state axis aiming at dent and friction force ripples using parameterized iterative learning control (ILC) for permanent magnet linear synchronous motor (PMLSM) executing same control instruction repeatedly. Velocity ripples are primarily attributed to periodic disturbances such as dent force and the gliding friction in PMLSM. The dent force...
Spindle-shaped lead selenide (PbSe) nanocrystals were synthesized by solution processing synthetic method for the first time. The prepared PbSe nanocrystals were characterized by X-ray diffraction, transmission electron microscopy and near-infrared absorption spectroscopy. X-ray diffraction pattern shows that the synthesized PbSe nanocrystals have cubic rock salt structure. Spindle-shaped PbSe nanocrystals...
