论文摘要
由于粮食安全问题，环境问题和经济学，提高农业效率是越来越多的优先事项。精确农业和可变利率应用技术可以在维持或减少肥料使用的同时提高产量。但是，这需要开发适合农业挑战的控制算法。在本文中，我们提出了一种新的生菜生长的开放模型，用于控制精确农业。我们证明了我们的模型是合作的，并且非常适合实验数据。 We use the model to show, via simulations, that a simple proportional distributed control law increases crop uniformity and yield without increasing nitrogen use, even in the presence of sparse actuation and noisy observations.
Improving the efficiency of agriculture is a growing priority due to food security issues, environmental concerns, and economics. Precision agriculture and variable rate application technology could enable increases in yield while maintaining or reducing fertiliser use. However, this requires the development of control algorithms which are suitable for the challenges of agriculture. In this paper, we propose a new mechanistic open model of lettuce growth for use in control of precision agriculture. We demonstrate that our model is cooperative and fits well to experimental data. We use the model to show, via simulations, that a simple proportional distributed control law increases crop uniformity and yield without increasing nitrogen use, even in the presence of sparse actuation and noisy observations.
