Microorganism identification is critical for the early diagnosis and management of infectious endophthalmitis, but traditional culture can yield false-negative results. Nanopore targeted sequencing (NTS) a third-generation technique with multiple advantages. This study aimed to test aqueous humour or vitreous fluid samples from presumed cases endophthalmitis using NTS evaluate feasibility in diagnosing especially culture-negative cases.This prospective enrolled patients who presented...
The deadbeat control is an effective way to promote the drive performance of permanent magnet synchronous machine (PMSM). However, problems time-varying electromagnetic parameters seriously affected accuracy model-based controller. Therefore, improved current method proposed in this paper. In method, we identify motor online through model reference adaptive system (MRAS) and use recognition results modify stator inductance flux linkage model. Simulation experimental demonstrate that has...
In order to improve robustness of permanent magnet synchronous motor (PMSM) servo system, a nonlinear generalized predictive control (NGPC) strategy based on extended state observer (ESO) is proposed. According the NGPC theory, controller designed by using continuous-time model PMSM. case parameter variations and external load disturbance in actual an ESO inverse hyperbolic sine function introduced estimate total system compensate dynamically real time. The simulation results show that...
In rail transit application, the performance of permanent magnet synchronous motor (PMSM) sensorless control system is limited by low switching frequency. this case, time-delay becoming more significant and degrades performance. To solve problem, a compensation method based on high frequency (HF) square-wave voltage injection strategy proposed in paper. Firstly, series filter used to extract HF response current, which can improve signal-to-noise ratio. Then, zero-order holder obtain current...

An adaptive filter is used as the speed loop controller for permanent magnet synchronous motor (PMSM) drive system to improve dynamic and anti-disturbance performance. The weightings of are adjusted by normalized least mean square (NLMS) filtering algorithm, so that transfer function equivalent inverse model controlled plant in system. At same time, transferred feedforward which makes can approximate plant. Then, control tracking realized. In addition, a second-order extended state observer...
In this paper, a three-loops position servo control method of permanent magnet synchronous motor (PMSM) for large aircraft cargo door actuator system (CDAS) is designed to improve the fastness and robustness system.First, an adaptive filter designed, weight adjusted by normalized minimum mean square (NLMS) algorithm, so that transfer function approximately equivalent inverse model current loop controlled motor, output used as compensation torque feedforward reduce impact external load...
