Path following is one of the key technologies of Unmanned Surface Vehicle (USV) to complete mission. The interference of flow is an inevitable environmental factor, the study of the straight path following of USV is aimed at enhancing the anti-interference ability of the path following control algorithm under the disturbance of flow. Based on the mathematical model of motion considering the influence...
The industrial gas heating furnace is a multivariable, nonlinear, strong coupling, parameter perturbation and time delay system. And its mathematical model is difficult to establish. On the account of these problems, a novel decoupling control method based on Small-gain theorem and Frequency domain function approximation is proposed. When the system of gas heating furnace was decoupled into three...
Using the information of gravity filed for aided inertial navigation can ensure the system's passive resistance and anti-jamming, and has become the hot topic of integrated navigation field. In this paper, we establish state-space model derived from the error equation of Inertial Navigation System (INS), and set the difference between indicated gravity anomaly and measured gravity anomaly which contains...
This paper presents results of an empirical study on the influences of staff's psychological factors to total quality management practices. SEM technique was used to analyze the data we gathered by face to face questionnaire investigation of manufacturing industry in Shanghai China. The results show that quality consciousness, staff's ability, Quality attitude and staff's interest have significant...
Advanced mathematics, as an important basic course in university, plays an extremely important role in fostering and improving the students' quality, ability, knowledge structure, logical thinking and innovative thinking. Based on years' teaching practice, and after investigating means of how to improve teaching quality for this subject and teaching style; Hereby we summarized these theory into six...
Rural regional development disparity has become a major development issue in China. As non-farm income is the main source of farm income and the key to solve regional disparity, our research focuses on farmers' non-farm income. While most existing research focused on micro factors that influence regional development disparity, our research explored macro factors, especially trade openness on non-farm...
According to mapping relationship of the relative internal efficiency of low pressure cylinder of condensing steam turbine and its affection, a mathematical model based on the Immune system's wavelet network was established. It can be used for calculating the relative internal efficiency of low pressure cylinder of 300 MW steam turbine. The application of the model shows that the proposed method is...
Based on researching into control technique of hematite flotation process, the mathematic model of control of flotation reagent quantum is introduced. This model uses image processing technique to extract texture characteristics of froth image before using the rough set and LVQ neural net technique to estimate the status of produce and adjust reagent quantum. Application of plant and emulate contrast...
