Research on Application of Fuzzy Neural Network in Combine Harvester

Abstract

Forward speed is an important factor influencing the productivity and quality of combine harvester in work process. Control the forward speed of combine harvester and keep the rotation speed of threshing drum in constant is effective both in improving production efficiency and threshing quality and reducing equipment failure. In this paper, the control method of rotation speed of threshing drum based on fuzzy neural network is introduced, and the fuzzy neural network controller of combine harvester threshing drum is designed. The simulation result shows that the fuzzy neural network control method is feasible. When the rotation speed of threshing drum is change abruptly, the fuzzy neural network controller can adjust the forward speed correspondingly in real time, in order to maintain the threshing drum works steadily in suitable rotation speed.
