The Visible Light Communication (VLC) is a good candidate technology for the application of Intelligent Transportation System (ITS). This paper focuses on typical application scenario between the traffic lights and lorry fleet. Based on the theoretical analysis and numerical calculation, we get the relationship between the speed of the lorry fleet and the conversion time of the traffic lights. The...
The control problem of underactuated spacecraft chaotic attitude motion is investigated based on exponential reaching law in this paper. First, the underactuated spacecraft chaotic attitude system is written in nonlinear equation form with two controls. Once the trajectory planning of angular acceleration is preset, the dynamics equation of angular velocity error can be obtained. Then, the sliding...
This paper first briefly introduces the basic structure of converter transformer, analyses the mechanism of vibration through simulation of the converter transformer oil-tank, designs the test scheme. This paper introduces the application of wavelet analysis method in converter transformer fault identification, then apply these methods to 24 converter transformers to obtain the characteristics parameters,...
Guidance is critical for a probe to land on the moon surface successfully. This paper mostly discusses about the guidance law in deceleration process of lunar soft landing. Based on some hypothesis, it creates the dynamics model which is built in the coordinate system of soft landing. Then the suboptimal fuel-consuming guidance law is designed for the purpose of reducing fuel consumption. Output errors...
After rendezvous and docking, the mass and mass center of target satellite can change greatly. In order to identify the mass and mass center of target satellite, research is made about the identification of mass and mass center about target satellite. As to the mass of target satellite, according to the information when the tracking satellite is located in different relatively stable position with...
