中文摘要:考虑开关设备组合作用下温室测控系统的非线性动态特性,提出了结构简单、不需复杂数值计算的离散预测模型,在不小于最大时滞时域内设备组合不变情况下,对设备组合进行滚动优化预测控制,从而大大简化了温室测控系统预测控制算法的复杂性,缓解了测控系统分布大时滞问题。仿真分析和温度的均方差表明,对分布式、大时延温室测控系统的优化组合预测控制方法是有效的。

Abstract:Considering the nonlinear dynamic response of the greenhouse measurement and control system based on switch devices combination control, a discrete predictive model was proposed. The model had simple structure and uncomplex computation. Within the time domain not less than the maximum distribution delay of the system, the devices combination was keeped invariably and optimized rollingly to carry out predictive control, so the predictive control complexity of the system was greatly simplified, the problem of long distribution delays of the system was relieved. The simulation analysis and root mean square of the temperature showed that the optimization combination predictive control method was effective for the greenhouse measurement and control system with long distribution delays.

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.
