to the complex topography, small plot size, rainy climate, and different crop sparsity in western China, sugarcane harvesting operations suffer from poor harvesting performance and unstable harvesting effect. Therefore, the power matching strategy of sugarcane combine harvester needs to be optimized to solve these serial problems. In this article, the whole power system of sugarcane combine harvester is designed, and the load-sensitive system control is used to improve the efficiency of the hydraulic system and optimize the power distribution. Meanwhile, this article studies the power control system and proposes a power intelligent matching strategy for sugarcane combine harvester to adjust the power output of the power system. The power intelligent matching strategy considers the harvesting conditions and system structure of the sugarcane harvester, optimizes the engine output power and operating point distribution by using filters and fuzzy control algorithms, uses an accumulator to store excess energy and replenish system power to precisely match performance targets for target harvesting conditions and improve fuel economy. The experimental results show that the sugarcane combine harvester with a power intelligent matching strategy can freely switch the working mode in upslope, downslope, sunny, rainy and various crop density fields, and meet the demanded power of each device by dynamically adjusting the working point of the engine according to the operating conditions, enabling the system to work better. The research method in this article can provide a theoretical basis for small sugarcane combine harvesters to harvest sugarcane in hilly areas, rainy seasons, and different crop densities.
