This paper is concerned with the calculation of the index weights for seafarers' competency evaluation model. The goal of our work is to obtain the reasonable index weight for the evaluation model. In this paper, firstly, the fuzzy comment data is prepared according to the fuzzy linguistic terms, and the intuitionistic fuzzy decision matrix is built. Secondly, base on the minimum intuitionistic fuzzy...
Cooperative guidance for multiple flight vehicles against single moving target is studied in this paper. Two finite-time consensus protocols are developed for multi-agent system with input saturation which underlay the design of cooperative guidance law. The cooperative guidance approaches are investigated to solve the many-to-one interception problem, where two novel guidance laws considering the...
Terrain-aided navigation is well known as an autonomous navigation method for aircrafts, missiles, underwater vehicles, and etc. The performance of iterative closest contour point (ICCP) algorithm is investigated in this paper deeply. The factors, including, the INS (inertial navigation system) precision, the map resolution, initial INS errors, the sonar accuracy, and the matching path length, which...
To obtain the attitude of spacecraft by a large field of view CCD system is not an unachievable task. The principal aim of this paper is to research the accuracy of spacecraft's attitude by shooting stars with the large field of view CCD system on the ground. In this paper, the quadrilateral algorithm model and an algorithm of data fusion from a set of real images, are given. The experimental results...
This paper proposes a new robot behavior where the servant robot runs alongside walls while it follows the human at a distance certain. The human shall give command using gestures at the same time. It changes its behavior depending on the command received. This behavior can make the robot appear more like a servant. The navigation uses fuzzy logic to estimate wall direction for robot control in an...
Take INS transfer alignment (trans-alignment) in powered phase of launch vehicle as example, suitability of two methods is compared in the paper. One is under launched point inertial coordinate, and the other is local geographical. Differences of state vectors choice, error-propagation, measurement model and influences of attitude maneuvers in powered phases under different coordinates are surveyed...
This After the alignment of the missile's inertial platform system, the inertial platform will be maintained in the inertial frame, this make the inspect of the platform misalignment hard to be achieved by using conventional algorithm. In this paper, an approach of misalignment self-inspect for missile's inertial platform is described. By using the in-motion alignment technique of strap-down inertial...
