The technology of Bank-to-Turn is an important development direction of hypersonic glide vehicles' control. But there is a strong coupling between roll channel and yaw channel when the vehicle is in rolling maneuver. In this paper, a dual decoupling fusion control method is presented based on aileron-rudder cross decoupling control and model reference global sliding mode control for the problem of...
Flexible accessories is an important part of modern satellite, the elastic vibration is the main factor influencing the control performance of space vehicle, which make it necessary to test the performance of vibration suppression for the control system on the ground. The difficulty of physical simulation is to simulate the space microgravity environment, the length of solar array is large and frequency...
Mobility models play a vital role in Vehicular Ad Hoc Networks (VANETs) simulations. Moreover, mobility models with higher extent of reality to fit into the characteristics of VANETs better make simulations more credible and accurate. However, most of traditional mobility models only devote to planar and ideal scenarios. It is rare for them to reflect more realistic environments, such as ubiquitous...
In this paper, we use the iterative learning control (ILC) algorithm to study the synchronization control of two Ghostburster neurons which are stimulated by two different external stimulus currents. At first, the periodic dynamic and chaos dynamic of two Ghostburster neurons are analyzed, which are stimulated by two situations of external stimulus currents. Then we design a kind of ILC controller...
Lodging in maize is one of the major problems in maize production worldwide. This study is to assess environmental lodging stress for maize based on probability analysis of extreme wind event in maize vegetative stage. A total of 687 growing counties in Huang-Huai-Hai Plain, China were chosen as study area. There were 148 meteorology stations with daily extreme wind speed data in recent 59 years....
This paper establishes the test models of individual effect and joint effect of the futures price volatility determinants on the basis of GARCH(1,1) model, and takes example for Wheat futures, and analyses empirically the relationship of futures price volatility and time to maturity, of futures price volatility and the day of week, of futures price volatility and volume and open interest. the study...
The distribution of data and knowledge of a huge amount of cultural heritage and the desire to make them available readily to people geographically scattered gives rise to the challenge of semantic integration of distributed digital museums. In order to make this difficult task tractable, how the participant museums are linked conceptually must be looked at first before any implementation issues for...
