In view of the precise trajectory tracking control problem for unmanned aerial vehicle (UAV), a control method combined nonlinear path-following guidance law with active disturbance rejection control (ADRC) is proposed in this paper. The method consists of outer trajectory control loop and inner attitude control loop. An improved nonlinear path-following guidance method is used in designing the trajectory...
This paper focuses on the use of a discrete simulation tool ( Simio ) to explore simulation of casualty treatment in wartime. Through the use of Simio simulation platform, visual simulation model of casualty treatment was developed, based on analysis of the casualty treatment task and process in wartime. Then, a personnel allocation in an operating room was tested using the model developed by simulation...
With the development of capacity and topology in shipboard power system, parallel running of multiple generators in single power station becomes an important configuration. The traditional protection method, with characteristic of off-line setting, sets the same values for several bus tie breakers. All generators would be step out while short-circuit occurs on bus-bar, which dissatisfies protection...
According to the Gauss curvature of each node on 3-D basic body surface, the indexes such as pheromone and volatilization coefficient are determined. The ant colony algorithm is designed and used. In the algorithm the selected nodes collection are changed every time. The circle times are determined based on the percent of desired nodes account for different areas. At last the basic body surface is...
