Abstract: With the development of modern agriculture, agricultural machinery has played an important role in improving production efficiency and reducing labor intensity. However, the energy efficiency optimization of traditional agricultural machinery still faces many problems and challenges. In this paper, the real-time monitoring and adjustment of various parameters of agricultural machinery is realized by introducing an intelligent control system, and the use of programmable logic controller（PLC） and predictive fuzzy control（PFC） technology to optimize the agricultural production process in terms of temperature, soil moisture and light intensity is elaborated to improve production efficiency, reduce energy consumption, and ensure crop quality and yield. The research results can provide technical support for the intelligent and sustainable development of agricultural production.
