Floor heating is a promising technique to heat greenhouses using low quality energy. The large thermal inertia of floor heating systems requires some form of predictive control. To analyze the effectiveness of feedforward logic, first a prediction model has been developed and then an experiment using a controlled-environment chamber has been conducted. Basic control logic has been established and verified for controlling air temperature by energy input only to the floor. The combination of feedforward and feedback control should be the next step.
