Phase-shifting reactor (PSR) can be used to solve the harmonic problems caused by rectifiers. In this paper, according to the active power balance principle, the relationships among the DC current of the loads, the currents of power supply side, and the capacity of core limb are built, the product specification of winding and core are obtained. Meanwhile, the coupled field-circuit method based on...
This paper describes a new technique for simulating the guidance of a SAM (surface to air missile) without the help of a controller. This analysis is fully automated in a closed loop using the features of commercial software MATLAB. The guidance algorithm is simulated with the help of aerodynamic data. Control law is not used for obtaining the desired deflections of the control surfaces rather reverse...
This paper aims to design efficient and effective approaches to virtual network embedding (VNE) problem, which deals with the embedding of a requested virtual network (VN) in an underlying physical (substrate network) infrastructure. When the node and link constraints (including CPU, memory, network bandwidth, and network delay) are both taken into account, the VN embedding problem is NP-hard, even...
Fault isolation and reconfiguration are very important aspects of distribution network automation. When there is a fault in the distribution system, the loads connected with the fault zone should be separated and the operation pattern can be found by changing the status of the section switches or contact switches. A method of using different fault isolation and reconfiguration measures to deal with...
It is very important for control system analysis and design to estabLish model and simpLified model of YiLiuShi neutraLization reaction process, which is characterized by critical nonLinearity and strong disturbance. In this paper, the nonLinear model with state-space expression is built based on neutraLization reaction mechanism, and its model is simpLified on the working point. Secondly, the controllabiLity,...
As companies continuously seek to provide products and services to customers faster, cheaper, and with better quality, the supply chain system is becoming recognized as a strategically critical aspect of the firm. supply chain encompasses all of those activities associated with moving goods from the raw material stage through to the end user stage. This includes sourcing and procurement, production...
This paper points out the existing problems in NDRR algorithm, puts forward an improved algorithm and conducts simulation contrast. The result shows the new algorithm can better solve the existing problems of NDRR algorithm.
The activation of neural ensembles in the cortex is correlated with behavioral states and a change in neuronal functional connectivity patterns is expected. In this paper, we investigate this dynamic nature of functional connectivity in the cortex. Because of the time scale of behavior, a robust method with limited sample size is desirable. In light of this, we utilize mean square contingency (MSC)...
Synchronization motion is the basis of hydraulic system of tensioner for pipelaying vessel during work. It is difficult to fulfill synchronization control. In this paper, an integrated PID neural network controller is proposed to achieve a synchronization of cylinders. The controller comprises an individual cylinder controller and a dual-cylinder coordinate controller, in which the individual controller...
To ensure the safety of pipeline in the laying process, a tensioner system for a pipelaying vessel was designed to realize the constant control to pipeline. The tensioner uses two tracks to clamping pipeline, hydraulic system to drive upper track, AC servo motor to send the pipeline into the sea. In this design, as the critical component of the tensioner, track shoe was designed; furthermore its strength...
Stainless steel is a kind of difficult-to-cut materials because of its low heat conductance, poor machining quality, serious work hardening, built up edge and tool wear. In this paper, the mechanisms and varying law of tool wear vs. cutting parameters in turning stainless steels with carbide tools is first investigated by performing the systematical cutting experiments and examining with SEM instruments,...
Combustion modeling is a very important method in designing internal combustion engine. In this paper, a multi-zone one with diagnostic and predictive functions is proposed for combustion in a gasoline engine. This model has been used to predict the performances and their changing with variable parameters such as ignition advance angle and coefficient of the residual exhaust gas respectively, in a...
Two different coding schemes including Bi-phase space (FMO) and Miller-modulated subcarrier (MMS) for Class 1, Gen 2 UHF RFID applications have been developed and correlated with the experimental results. The functionality of the Miller-modulated subcarrier (MMS) and FMO designs are verified using verilog hardware description language. In addition, the simulation results for the power performance...
In order to suit multivariate market, Steel plants are forced to organize multi-mode production, which makes the production logistics in plants becoming more complex. This made the slab-yard becoming very important in steel production, orienting to a new steel plant, simulation technology is used in slab-yard. First, the simulation target is made. Then simulation models under different production...
