Design of motor-driven precision seed-metering device with improved fuzzy PID controller for small peanut planters

Traditional passive ground wheel drive of peanut planters has displayed poor high-speed seeding performance and the slippage caused in case sticky wet soil. Given this, an integrated electric-driven precision seed metering device controller were designed, which features application improved fuzzy PID algorithm. Based on a small planter with one ridge width duplicate rows, servo motor is used to replace traditional wheel. In addition, satellite speed measurement employed complete electric driving controlling modification meter precise control. A working process mathematical model for was established conduct field tests aim at comparing performances between conventional controls. The trial shows that average error actual ±1 rad/min, coefficient variation less than 1%. Against one, it can better suppress overshoot improve response speed. stable output still be obtained even step changes. Field show when medium low speeds, qualified rate plant spacing greater 98%, missed sowing <2%; while high speed, 94%, 4%. qualification increased by 6.72%; compared other meters, 4% during sowing. summary, this study provided effective technical reference planting peanuts.
