Intelligent control based on case-based reasoning for outlet tobacco moisture percentage of loosening resurgence machine

Tobacco loosening and resurgence process has strong nonlinearity and large delay-time ratio, and it is difficult to describe the process via accurate mathematical models. Thus, it is difficult to control the outlet tobacco moisture percentage (OTMP) for loosening and resurgence machine by operators. To solve these problems, combining the expert knowledge and operation experience, an intelligent control method based on case-based reasoning (CBR) is presented for loosening and resurgence machine. The intelligent control method is applied in certain cigarette plant which shows that the OTMP is controlled in the scope of target value and water consumption is reduced.

Design of intelligent control system for Vertical Roller Mill

In order to help the Vertical Roller Mill (VRM) working stably with higher automation level and lighter labor intensity, an intelligent automatic control system is designed by analyzing the characteristics and technology of the VRM grinding process, where both start/stop operation and normal work can be executed in automatic mode. Besides, Interlock protection is introduced so as to improve the security of the proposed system, which has not only improved the automation level of VRM system, but also guaranteed the stability and reliability effectively.
