温室环境动态模型精确分析解初探

温室环境动态模型是研究温室节能、结构改进及其参数控制的有效方法。我们以传统迭代法为基础，试用新兴的强有力的计算机符号解法来求解模型。结果表明，在ＩＢＭＰＳ／２计算机上，符号处理和传统迭代法所模拟的结果之间的最大误差小于０．１＇乙模拟一天的时间从原来的１５秒减少到８秒，而且使求各参数对温室气候的影响更为方便，并且为进一步把模型应用于实际调节控制打下了基础。

Initial studies on the exact analytical solution of a grefnbouse environmental dynamic model

A greenhouse environmental dynamic model was an effective method to study the energy saving,the structure improvement as well as the parameters control of the greenhouse. Based on the traditional iterative method,in this paper,the model was tried to be solved by using the microcomputer symbolic manipulation which was a new and powerfuI tool.The resuIts showed that the simulated temperatures between the traditional iterative method and the svmbolic solution agreed within 0.1'C,and the simulation time of a whole day had been shortened from 15 seconds to 8 seconds on IBM PS/2. It became more convenient to get the affection of the parameters to the greenhouse climate and to apply the model to the practical environmental regulation and control.
