Antenna's servo-control system based on aeroboat is a 3-loop DA mixed control system composed of position feedback, velocity feedback and current feedback. The system combined with stabilized loop and tracking loop realizes real-time pointing movement of the antenna. To eliminate the effect on aiming at the target of aeroboat motion, the server-control of 3-axis angle position is realized based on...
Collaborative learning is a new teaching mode that comes into being under the contemporary teaching circumstances. It is important to improve student's creative ability, cooperative spirit and improvement of utilization of the learning resource. Through the research on the connotation of collaborative learning and SOA methodology, this paper analyses their common characteristics and gives out a model...
Crossed cube is a variation of hypercube, but some properties of the former are superior to those of the latter. However, it is difficult to extend the scale of crossed cube networks. For example, it is necessary to double the number of nodes to extend the scale of crossed cube networks. As a kind of hierarchical ring interconnection networks HRN, crossed cube-connected ring interconnection network...
Professional synthetic training (PST) is an important part in engineering education. It intends to enhance integrative experiment and designing experiment for students. It covers a wide range of professional courses and overcomes the drawbacks of traditional teaching, such as attention to the experiments of their own independent course and theorems verification. PST course based on working process...
In this paper, a method is presented for connectively analyzing the dynamic factors in physical training by utilizing computers. Through analyzing the training results of a certain triple jumper, the thesis expounds how to build the mathematics models for the connective factors in system and it also presents the detailed procedure by utilizing these models to connectively analyze the dynamic changes...
How to select athletes has always been an important research subject in sports activities. And this paper explores one related analytical method in which the computer is applied to every dynamic element while choosing sport equipments. And through the example of jump athletes, building the mathematical model of systematical related elements and the steps which uses this model to analyze the dynamic...
Crossed cube is a variation of hypercube, but some properties of the former are superior to those of the latter. However, it is difficult to upgrade crossed cube networks. For example, it is necessary to double the number of nodes to upgrade crossed cube networks. As a kind of hierarchical ring interconnection networks HRN, crossed cube-connected ring interconnection network CRN can effectively overcome...
