摘要：

Linear system identification methods based on Laplace transforms and Pade' approximations are used to determine the spatio-temporal responses of a Venlo glasshouse to gaseous enrichment. It is shown that the method for distributing CO2 in the glasshouse by using a low level ring main with a distribution pipe along the crop rows is adequate for uniform mixing. The analysis also indicates the maximum rate at which the CO2 set point can be updated dynamically for the proper execution of on-line optimal control of CO2. © 1992 Silsoe Research Institute.
