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.
