This paper analyzes the process and control of nanohydrogen storage alloy strip rolling. We design a nonlinear model of rolling mill, use the neural network control scheme, and we adopt the rolling process of mathematical modeling, and use the model of the mathematical method in quantitative analysis. Finally, we use the system of computer simulation, at the end we draw the following conclusions. In strip rolling process, using a neural network system for control, far superior to the introduction of PI control, not only solved the rolling process with variable delay and variable gain and other shortcomings, and that the hydrogen storage alloy electrochemical performance was improved, the production process to ensure the high quality of hydrogen storage alloy, reducing energy consumption, saving raw materials, reduce the labor intensity of operating staff is of great significance.

This paper introduces the composition of double closed loop DC speed control system of DC motor speed and current, it is described the working principle of DC PWM converter and the calculating method of the pulse width modulation technology. Using the Matlab software to the induction motor system of modeling and simulation based on the technology of SPWM . Observed in the steady state and dynamic system using SPWM control mode and the influence of control parameters. Finally, experimental results show that the SPWM technology for effective control of double closed loop DC speed control system

In the Ni-MH power battery electrodes manufacturing, the quality of the electrode material admixture will affect electrode and the whole function of batteries directly. However, the electrode material admixture process is very complex. It is very difficult to build up a model of precision to carry on control to the system. The traditional electrode material admixture control of the process, mainly according to develop the personnel on trial and the spot experience to complete, That method basically can not reach the good control appearance. The Fuzzy control can resolve the problem of this complication nicely.
