The Development of an Electric-Driven Control System for a High-Speed Precision Planter Based on the Double Closed-Loop Fuzzy PID Algorithm

In order to solve the problems of traditional seeders, such as low seeding efficiency, tangled straw, a large amount clay, easy ridge breakage in sowing operations, qualified rate high-speed seeding, and poor uniformity, this paper takes pneumatic corn planter research object, Beidou automatic driving unit carrier, CAN (Controller Area Network) bus communication medium, double closed-loop fuzzy PID (proportion-integral-derivative) algorithm control core designs precision system based on navigation. It solves that exist planters. bench experiment, stability is judged by comparing motor accuracy with ordinary measuring response time at different speeds. The test results show when theoretical speed 0~34 r·min?1, shortened 0.51 s compared control, error between actual target value less than 0.35%. field experiment runs for 5~13 km·h?1, average planting spacing greater 95.81%, reseeding 10.11%, coefficient variation 16.72%, which complies standard operation.
