In this paper, we make the interlayer of the boiler in AE2000 process control device produced by Zhejiang SUPCON Electronic Technology Co. as object. The interlayer temperature control has characteristics of lag, nonlinear, vulnerable to disturbance and so on. Considering that the PID control is not effective to the temperature control, a fuzzy adaptive internal

Copper is raw material of great strategic significance in the national economic development and security. Because of the shortage of copper resources in our country, regeneration of scrap copper in an efficient, clean, energy saving way is the only outlet. However, the existing scrap smelting process is of high energy consumption, labor-intensive, serious environmental pollution,
