Self-adaptive Inversion Control for Continuous Flow Grain Drying

摘要：

Grain drying is a nonlinear process featuring with multi-variables and long delay. Moisture content as one of the key set variables in the drying processes is difficult to be controlled accurately.Since classical control methods based on mathematic model are not suitable for this kind of nonlinear process, a new intelligent control system for continuous-flow dryer was proposed to solve this problem.Based on the human control concept for controlling the outlet moisture content, a human-in-the-loop self-adaptive inversion control model for grain drying process was established, a nonlinear process inversion control algorithm was composed, and consequently a human-in-the-loop controller for continuous-flow grain drying was developed. Experiments have been conducted and the results showed good feasibility of this control method.
