Two-phase hybrid stepper motors for aircraft are frequently used in electrically driven valves. Microstepping control is to improve the accuracy of motor. However, different decay modes affect efficiency, vibration and noise drive system. By analyzing mechanisms each mode, suitable models types motor proposed. The analysis results realize trade-off among microstepping noise.
This article proposes a multi-input multi-output digital control strategy for bidirectional interleaved boost converter with coupled inductors, designed to operate as an interface between ultracapacitor and high-voltage dc-bus in hybrid nanogrid. The keeps the side of nanogrid stable when voltage at low-voltage side, connected ultracapacitor, changes wide range. Bidirectional energy flow current protection is allowed too. regulation loop closed around inner, loop. In parallel these, third,...
Based on the current research development of CPS (Cyber-physical System) and idea systematic structure, this report focuses real-time feature task model. The methodology Real-time tasks scheduling is proposed in paper, particularly, system networks solution will be explored from angles heterogeneous convergence, networking protocol network processing algorithm.
This article presents the topology and control of a three-port energy gateway (EG) for hybrid ac/dc nanogrids. The simple hardware architecture allows connecting renewable generators, storage (ES) devices, such as ultracapacitors, utility grid through three different interface converters, which, altogether, define EG nanogrid. proposed represents tradeoff between circuit complexity controls flexibility, allowing: 1) operation ES port over wide voltage range; 2) local dc-bus at predefined...
In order to improve the position servo performance of permanent magnet synchronous motor (PMSM) control system, current loop and in PMSM system are optimized. eliminate influence d-axis q-axis cross-coupled potential on dynamic inner uses decoupling with voltage feed-forward compensation added traditional PI control. Servo motion ultimately pursues accuracy outer so should take into account tracking system. speed acceleration is introduced for An experimental platform set up research carried...
This paper derives the generalized average modeling and analytical small-signal transfer functions of Bidirectional Interleaved Boost with Coupled Inductors (BIBCI) converter, all which is then compared previously presented nonlinear models. Theoretical results are verified via simulation actual experiments, thus proved to accurately predict converter dynamic behavior.
Recent development of MeRIP-Seq enabled the global unbiased profiling transcriptome-wide N6-Adenosine. With this technique, it is now possible to detect RNA methylation sites under a specific condition or differential between two experimental conditions. However, as an affinity-based approach, has yet provided base-pair resolution. A single site reported by data may actually contain one few methylated residuals, which cannot be differentiated existing analysis methods when entire treated...
For sensorless control of brushless DC (BLDC) motor, the accuracy commutation point identification has a vital impact on performance and load capacity. The relationship between terminal voltage waveform deviation is analyzed in case advanced or lagging commutation. detection error zero-crossing due to spike analyzed. Therefore, new correction strategy based back-EMF presented. By means keeping symmetry voltage, corrected by controlling delay angle signal closed loop. This offers some useful...
The article proposes a modulation strategy (MODUS) that can realize the integrated control of brushless DC motor(BLDCM) motoring and braking. Using this strategy, motor freely switch between braking states without additional commands, which is great significance for application BLDCM in automatic driving or constant-speed cruise. For convenience explanation, firstly, MODUS state existing method introduced. Then, an proposed its working principle analyzed. Finally, effectiveness verified by...
