ADAPTIVE CONTROL OF GREENHOUSE CLIMATE |
| Author: | H.-J. Tantau |
| Abstract:
A microcomputer system has been developed for greenhouse climate control. In a first step programs have been written and tested to improve the greenhouse climate control. A simplified mathematical model of the greenhouse is used in order to calculate the influence of outside weather conditions on the inside climate. The comparison of calculated and measured values allows a continous adaption of the parameters of the model. Besides this adaptive control-algorithms are used. By means of the model a gain factor of the system is calculated for tuning the controller in order to get a constant gain of the control loop avoiding oscillation. | |
