摘要：Rice seed soaking and germination is a crucial process before sowing in the cold area where rice is widely cultivated. Temperature controller of rice seed soaking and germination device requires a high performance in precision and stability, for the quality of soaking and germination has a great influence on the cereal yield. In this paper, grey-box model combined with sliding mode control (SMC) method was designed for rice seed soaking and germination device. The grey-box based sliding mode controller was simulated in Matlab based on a nonlinear auto regressive external (ARX) model of the device, performance of different control parameters were compared. Comparative study of a SMC controller, a proportional-integral-derivative (PID) controller, and the proposed scheme was carried out. The results showed that the grey-boxed based sliding mode controller had a superior performance, due to its faster convergence and stability. The experimental results showed that the proposed method achieved an expected soaking and germination quality.
