Inertial Navigation System (INS) algorithm can be used for curve measuring system based on a single-axis Fiber Optic Gyroscope (FOG). The trajectory calculation is performed with an assumption of neglecting the length of the carrier employed in the measuring system. The limitation of this assumption will be explicit for particulars cases. A mathematical model is proposed to study the deviation caused...
Pedestrian traffic system is a stochastic dynamic system with uncertainty cluster density, non-linear and the interaction among the individuals. Now computer dynamic simulation is one of the effective methods to study the mechanical characteristics of pedestrian flow in the public buildings. Aimed at the problems that under the same scene different software tools used in pedestrian simulation may...
A low-end MCU base power factor corrector (PFC) is proposed in this paper. Due to green power issue, PFC is more important, but need an extra controller to achieve. However, in most electric equipments and appliances, the MCU is used to accomplish key functions or handle user interface. The structure and control strategy proposed in this paper is based on the rest calculation resource of the MCU build...
It is a trouble thing to build theoretical model for stir characteristics of screw axis with variable diameters and different pitches, so a called PSO-BP neural network (NN) model was employed. In this mode, particle swarm optimization (PSO) algorithm is used to train weights and thresholds of artificial neural network instead of BP algorithm, to overcome drawbacks of BP algorithm. To avoid the slow...
A design example of voltage and reactive power fuzzy logic controller for 110 kV substation based on MATLAB is done in this paper. 56 fuzzy control rules are extracted on the basis of nine-area diagram divided the area of prior switching of capacitors. MATLAB fuzzy logic toolbox is used to build fuzzy logic controller's fuzzy inference system and MATLAB SimPowerSystems Blockset is used to set up a...
To solve those traffic accidents during conscious lane change of vehicles on highway under dangerous conditions, a new safety lane change model is established on the basis of the lane departure warning system which Jilin University has developed. This model is studied under a typical scenario on highway, and also considered with the actual driver behavior that most vehicles always accelerate during...
The 800,000 t/y Ethylene Project in Wuhan, launched by Petrochemical Industry in China, is one of the major projects of national development strategy. Within the following five years, China will construct the largest petrochemical industry base of Central China in Wuhan by allotting 300 billion key funds around the industry chain of this project. According to the content of project construction, the...
