Farmers face a constant battle – ensuring their crops receive the right amount of pesticide or fertilizer, while minimizing waste and environmental impact. A new high-performance boom control system tackles these challenges by keeping spray booms precisely positioned during operation.
The Challenge: Uneven Terrain and Spray Drift
Traditional spray booms often struggle to maintain a consistent distance from the crop canopy due to uneven terrain. This can lead to uneven application of the spray, potentially missing target areas or over-spraying, leading to waste and environmental concerns.
A Technological Solution: The Active Boom Control System
Researchers have developed a sophisticated active boom control system specifically for booms with a trapezoid suspension system. This system utilizes a combination of hardware and software components to precisely adjust the boom’s position in real-time.
Under the Hood: Hydraulics and Control Algorithms
The system comprises a hydraulic system with strategically placed cylinders and a control unit powered by a unique algorithm. The researchers developed mathematical models to simulate the behavior of the hydraulic cylinders and the boom suspension itself. This allowed them to optimize the system’s design and identify key parameters for its operation.
Fine-Tuning Performance: The FPID Control Algorithm
A critical element of the system is the control algorithm. The researchers opted for a Feedforward Proportion Integration Differentiation (FPID) algorithm, which is known for its ability to improve tracking performance. This means the system can anticipate changes in terrain and adjust the boom accordingly, ensuring consistent spray application.
Putting it to the Test: Real-World Performance
The new system was installed on a 24-meter boom sprayer with a trapezoid suspension. Extensive testing evaluated its response to various stimuli, including step signals and sinusoidal signals. The researchers then conducted field experiments in challenging terrain, analyzing the system’s ability to maintain boom stability.
The Results: Precision Spraying Achieved
The field tests were a resounding success. The system effectively minimized the boom’s inclination angle, even in challenging terrain, ensuring a consistent spray pattern. This translates to more precise application of pesticides and fertilizers, minimizing waste and environmental impact.
A Brighter Future for Farmers
This innovative active boom control system offers significant benefits for farmers. By promoting precise spraying, it reduces waste, lowers costs, and minimizes potential environmental damage. Additionally, the system’s ability to handle uneven terrain allows for more efficient spraying, maximizing productivity. This technology holds promise for a future of sustainable and efficient agricultural practices.
