A visual servo control system based on CAN-bus is designed to fulfil the manipulation for blocking plate in nuclear power plant. In the past, workers have to stay in the steam generator for a long time to assemble the blocking plate, which will have a great of harmful influence on the health of workers. In order to reduce the residence time in high radioactive region, a kind of robot is demanded to substitute workers to finish the job. To improve the accuracy of control system and realize the automatic operation, visual servo method is applied to optimize robot control system. Based on the prototype, experiments were conducted to verify the performance of robot system. The results showed the validity of optimized robot control system and the feasibility of automatic operation.

The boiler system in power plant consists mainly of a steam-water system and combustion system, which produce a high-pressure superheated steam to drive a generator in order to produce power. The steam temperature control of the boiler system is a critical operational consideration. Parameters of boiler producing process must be controlled strictly. But the boiler system has high nonlinearity, large delay, strong coupling and load disturbance. Therefore it is difficult to develop practical mathematical model of the control object using the traditional PID control. In order to realize the optimal control of steam temperature, this paper presents the adaptive fuzzy-PID control Strategy. Simulation results based on MATLAB show that the proposed strategy can largely improve the system response performance compared with the traditional PID control

Use of aerodynamics, air flow spectrum and gives the car body surface of the vehicle surface pressure distribution of the site prone to dust contamination was analyzed, designed body structure, and reduce eddy current flow separation zone, the body surface can be reduced dust pollution, body structure designed to provide a reference.

According to the different specifications of capacitor frame structure similar, designed by different designers, it will cause unnecessary duplication of labor, long design cycle, high cost, and the probability of error is relatively large, probably the same problem recurring. It causes not only the waste of manpower and resources, but also the existence of manufactured parts cannot be assembling a series of follow-up questions, it needs to be modified to normal use, causing great resistance to the research and development of new products. So that the competitiveness of enterprises in the same industries was at a disadvantage, based on the secondary development of Pro/E to solve the above problem.
