Fuzzy Control of Air-Suction Seeding Device Based on SPCE061A

Abstract

In order to make sure the seeding quality of air-suction seeding device, it is very important to control the vacuum degree of sowing drum. In this paper, the structure and principles of air-suction seeding device was introduced briefly and a fuzzy control system to control vacuum degree based on SPCE061A was presented. According to the features of SPCE061A and control demands of seeding device in the seedling production line, a new control technique combining speech control with fuzzy control was proposed to control seeding device. A layout about two-dimensional fuzzy controller was described. The dynamical simulation was carried out by using the MATLAB fuzzy toolbox. The result of simulation demonstrated that it was feasible to adopt the method of fuzzy control to control the vacuum degree of sowing drum in air-suction seeding device.
