DC transformer (DCT) is the main and key equipment of DC distribution network. Multi-ports DCT can connect multiple DC lines or networks at the same time, which has high power supply reliability and is suitable for interconnection equipment among different DC power grids. As an important node in DC distribution network, multi-ports DCT not only operates under normal conditions, but also needs to deal with the impact of DC system fault, among which short circuit fault is the most common one. In this paper, the short-circuit characteristics of multi-ports DCT operating in three different modes are analyzed. The analysis shows that when a single port of the multi-ports DCT fails, the fault ride through of the multi-ports DCT cannot be realized only by changing the operation mode to block the port. This paper investigates a fault ride through strategy based on solid state circuit breaker and feedforward decoupling control method. The simulation results verify the fault characteristics of the multi-ports DCT under different operating modes, and verify the effectiveness of the proposed fault ride through strategy.

Due to the complexity of war and the variability of operational requirements, the parameters of any mathematical model to study warfare need to be adjusted according to the actual situation of war. Operational capability index model is an effective formula to evaluate the capability of combat system, and the current parameter calculation method of this model has a high time complexity. Based on the characteristic topology analysis, this paper presents a fast method to fast determine model parameter. Compared with the parameter calculation method based on genetic algorithm, the accuracy is similar while the speed is greatly improved.

Obstacle detection based on 3D-Lidar is an important sensing means of automation navigation. In rough terrain, due to the unstructured characteristics of the field environment and the bumpy road, it is difficult to accurately detect obstacles by Lidar in a single scan. Meanwhile the reconstruction of obstacles in the blind area of the sensor is also a key problem of autonomous navigation for safety. We propose a 3D-Lidar based obstacle detection and fast map reconstruction method to solve these problems in rough terrain. First, point clouds are projected onto the 2D grid map of overhead view. we use gradient statistics in the height direction to obtain a basic obstacle detection result. Then according to the obstacle detection result in single frame, the proposed method uses Bayesian probability calculation based on the first-order Markov model for perception map reconstruction. The final perception result consists of the current frame perception result and historical results by map reconstruction. And a probability map on the confidence value of obstacle is generated rather than the traditional binary grid map of obstacle and obstacle-free area. This method has high robustness for obstacle detection in rough terrain and can effectively solve the problem of environmental perception in unstructured scenes. In addition, obstacle in the blind area of the sensor is retained by map reconstruction to ensure the safe driving of the UGV. The calculation period of the method is within 100ms and meets the real-time requirement for autonomous navigation of the UGV.

Capsule robots have broad application prospects for interventional diagnosis and treatment in the gastrointestinal tract. This paper proposes a dual hemisphere capsule robot driven by a pure magnetic moment. Its structure features that the upper and lower hemisphere, which can relatively rotate freely, constitutes a coaxial body, thus the dual hemisphere capsule robot can realize panoramic observation during the suspended posture adjustment in passive mode and rolling locomotion in active mode. The dynamic equation for attitude control is established based on the analysis of the magnetic moment, damping moment and gravity moment models of the dual hemisphere capsule robot, thus the influence on the dynamic characteristics by the center of gravity offset is studied particularly. The research results show that when the center of gravity of the dual hemisphere capsule robot moves along its axis, the orientation of the dual hemisphere capsule robot axis can still be controlled by changing the normal vector of the rotating magnetic field, and the dual hemisphere capsule robot axis will make regular precession in the stable state. This research has laid a solid foundation for the reliable application of the dual hemisphere capsule robot.

This paper presents a switched fuzzy adaptive double coupled sliding mode approach for longitudinal control of a platoon with a leader vehicle and multiple followers based on third-order model with bounded external disturbance. For the purpose of avoiding collisions between vehicles, some control strategies are designed to guarantee the strong stability of the whole platoon system. First, in order to guarantee the strong string stability of the platoon system, a condition for coupling coefficients of sliding mode surfaces about adjacent vehicles is given in the paper. Then, the control law employing double coupled sliding mode control is designed for the stability of every vehicle in the platoon and the corresponding theorem is proved in the paper. Moreover, for the development of the chattering problem in the sliding mode control which becomes severe as the boundary of the disturbance increases, a novel switched fuzzy adaptive double coupled sliding mode control is proposed in this paper by using the universal approximation property in fuzzy system. Finally, some numerical examples are finished to verify the validity of the proposed method.

In recent years, with the rapid development of the UAV manufacturing technology, great progress has also been made in the Quadcopter. Usually, the small Quadcopter is flexible and easy to be operated. The stability is one of the most important evaluation indexes for the flight quality of the Quadcopter. However, external environmental impacts (such as the wind power) or internal design problems often cause the Quadcopter to deviate to one side during the flight. Therefore, in order to solve this problem, this paper adopts the method of physical weight gain and low-cost design. Then, we did experiments in the windless condition indoors and in the windy condition outdoors. We test and analyze how weight gain affects the Quadcopter’s flight stability. By comparing the test group and control group, we find that test group is more stable and faster than the control group. Also, the experiments show that when the weight of the Quadcopter increases, with the help of the low-cost design and the mathematic model, the flight offset can be reduced to 20% at most. Thus, the flight stability of the Quadcopter is improved as well. In addition, our stability design is not affected by the environment. Also, this design doesn’t need to change the internal structure of the Quadcopter.

Continuum robots are usually made of flexible materials. In theory, there can be an infinite number of degrees of freedom. There are no discrete joints and rigid links. Therefore, they have good flexibility, sensitivity and operability, and can adapt to small space operations and highly nonlinear structured environment operations. In this paper a two-joint decoupling kinematics analysis method for a line-driven continuum robots with four drive lines is proposed. The end position and the length of the driving line of the single-joint and two-joint manipulators are simulated experimentally, and the feasibility of the proposed decoupling kinematics analysis is verified.

The increasing number of wireless sensor nodes brings more application markets and challenges to the Internet of things (IoT). The traditional IPv4 address resources cannot meet the needs of the development of the IoT, so we need a communication mechanism with better compatibility and scalability. With the proposal of the 6LoWPAN protocol, the application of 6LoWPAN to the communication network of the IoT has become the focus of research. This paper studies the research status of 6LoWPAN in the field of Internet of things in the past four years, and analyzes the system architecture, system composition and monitoring parameters of 6LoWPAN through different application scenarios. Experiments in related literatures show that 6LoWPAN has stable network transmission performance and can be used for precise monitoring and management in combination with web applications. In addition, RPL routing protocol security algorithm can be one of the future research directions.
