The high-mode experiment can be obtained by heating the plasma with the auxiliary heating system in the controlled nuclear fusion research. The performance of the auxiliary heating system can be affected by the output of main high voltage pulse power supply. The high-voltage pulse power supply based on Pulse Width Modulation (PSM) technology has the advantages of high effective frequency and little energy storage of the filter system. It is of vital importance that the stored energy released to the load should be very little when some protections occur. The power supply will be connected to the load when the IGBT is out of control, and the AC source energy will be transformed to the load through the air switch. So the air switch should be triggered to disconnect from the AC mains. The control board can detect the IGBT operating condition by the IGBT drive signal, output signal and control signal. So control board can be used to trigger the air switch in a short time, and the energy released to load is very little, which ensures that the load is very safe under protecting.

The key of microbial breeding is how to quickly select the target colony from the mutant library. High-throughput clonal colony selection technology is to solve this problem. The selection of clonal colonies is a key link in biotechnology, and it is also a very heavy workload. The traditional picking method is manual, which has low efficiency and low precision. Compared with manual picking, the automatic screening and picking of colonies by robots can greatly improve the production efficiency and picking accuracy. In this paper, a robot is designed, which can quickly pick out cloned colonies. The robot can carry out picking, inoculation, cleaning, sterilization and drying at the same time. It uses servo motor and pneumatic drive mode, combined with machine vision to coordinate the colony positioning and the multi-axis motion control cardcontrols the cooperative work of all parts of the robot, and equipped with a variety of sensors to assist the operation of the robot.

The article researches on the energy control strategy of Energy control strategy of four-wheel drive Vehicle with Series-Parallel hybrid power system based on pattern classification. A kind of four-wheel drive hybrid system whose structure is front axle driven by series-parallel hybrid system and rear axle driven by a single motor is designed, and its components are introduced. In addition, mode switching boundary and mode switching dynamic control are designed. According to the system efficiency, the operating points of the powertrain in each mode are optimized. Finally, the economy of the system is verified in a variety of working conditions by vehicle test, and the energy-saving mechanism are verified through the analysis of working condition characteristics, working mode proportion and operating point distribution.

An automatic feeder for poultry farm with digital display, adjustable temperature and humidity and timing function. It is mainly composed of feeding mechanism, feeding mechanism, travel mechanism, temperature humidity and electrical control box with digital display, can display 24 hours, and with time setting function, in the case of a single intervention to perform automatic feeding work, reduces the labor cost, not only can reduce the time of staff contact with poultry, reduce the spread of disease. With a temperature humidity sensor at the same time, the real-time monitoring and display of breeding field numerical, temperature and humidity can be set to allow upper and lower limits of temperature and humidity fluctuations, and according to the set point control spraying water pump, fan, or heating equipment synchronization work, simplifies the operation of separation equipment, precise control of the feeding environment of temperature and humidity value, achieve the goal of the poultry feeding scientifically.

Supernumerary Robotic Limbs (SRL) can expand the physical capabilities of humans in various tasks and working environments. To increase the operation efficiency of SRL, it is critical to acquire task and environmental information, which limits the controller. Previous research has proved that the gaze signal plays a vital role in human-robot shared manipulation. Therefore, this paper proposes a gaze information based controlling system for SRL. This system consists of the following modules: gaze information acquisition module for capturing gaze and environmental information, spacial transform module for transforming the position of gaze target to SRL working space, and SRL execution module for sending commands to SRL. The experimental results demonstrate that the proposed system could control SRL based on the human gaze. The total mean absolute error between gaze position and actual execution position is limited to an average of 26 mm/m (2.6%). These results indicate that eye-gaze can be used to control SRL, which is beneficial for promoting the controlling efficiency of SRL and expanding application possibilities of SRL.
