A predictive system for feed quantity of combine based on fuzzy neural network was proposed to solve the delay problem of measuring feed quantity. This paper constructed the predictive system according to the actual destination and then decided the input and output of the network and its fuzzy dividing. At the same time, this paper investigated the construction of fuzzy rule base and designed the...
Vibrating sieve is one of the main parts of a combine. When the types or parameters were changed, the whole model would be changed. In this paper, the three-dimensional parametric model of vibrating sieve was established based on UG. Then the custom menus, UIStyler dialog boxes and control procedures were designed by using UG / Open API secondary development. In the environment of VC6.0, the main...
The main concern of this paper was to establish the force model of seeds motion during the sucking process and to find different factors impacting seeds suction performance. Then the mathematical model of forces acting on seeds during the sucking process was established in order to optimize the working parameters including the sucking force F, the rotational speed of cylinder ω and the position angle...
According to the actual situation of combine harvester workload, a load feedback controller based on theory of fuzzy control is designed by means of detecting the information such as threshing cylinder speed, crop screw conveyor speed, feed-in quantity, loss rate which can reflect the workload of combine harvester and researching on multi-signal fusion method. It can auto-control the forward speed...
