When combine harvester is used in the field, the load is difficult to be stabilized due to the complex environment. Based on the analysis of the cylinder power model, this article identifies the factors that affect load stability. We calculated and studied the fuzzy control of the cylinder load.Cylinder two-dimensional fuzzy controller is established through the Matlab, and the cylinder fuzzy control model is set and simulated through the Simulink, which results prove that the fuzzy control of harvester load stability is accurate and effective.
