Moisture content is one of the key controlled variables in grain drying processes. However, this variable cannot or is difficult to be controlled accurately, due to grain drying is a nonlinear process with multi-variables and long delay. To solve this problem, the study is focused on a new intelligent control system for continuous-flow dryer. Based on the manual control idea for controlling the outlet moisture content, a nonlinear process intelligent control algorithm is presented, a human-in-the-loop intelligent control model for grain drying is developed, a system of software structure based on Visual Basic 6.0 is designed.

At cementing of casing of oil and gas wells during the process of injecting of cement slurry in the casing column the slurry can move with a higher speed than it’s linear injection speed. A break of continuity of fluid flow occurs, what can lead to poor quality isolation of producing formations and shorten the effective life of the well. We need to find some technical solution to stabilize the linear velocity of the cement slurry in the column. This task can be resolved with an automated control system.
