中文摘要:针对生物质气化炉处理过程中存在非线性、大时滞性、不稳定性和负荷干扰特点,提出了一种基于灰色蚁群组合预测双闭环控制算法。首先采用灰色算法建立气化炉温度预测模型,然后考虑可能的扰动,引入蚁群算法对灰色模型进行优化,在此基础上对炉温进行控制;最后引入基于变论域模糊控制算法,利用模糊规则对气化炉一次风量进行控制,在保证炉温稳定的情况下,降低可燃气体含氧量。仿真和现场运行结果表明了方法的有效性和先进性。

Abstract:The process of biomass gasify has the characteristics of nonlinear, large delay and strong load disturbance. For these features, a double-loop intelligent control based on gray ant combination prediction algorithm was presented. Firstly, the gray prediction algorithm was used to establish temperature model of gasifies. Secondly, considering possible disturbance, the ant algorithm was introduced to optimize the gray temperature model. The temperature sub-control system was based on the optimized gray temperature model. Finally, the variable universe fuzzy control algorithm was used in the oxygen content sub-control system. The gasify-air was controlled by the fuzzy rules in order to stabilize the temperature of gasifies, and reduce the oxygen content of the combustible gases. The validity and superiority was showed in the results of simulation and work site.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
