Abstract: In many temperature control systems for rooms, proportional-integral control is often used and a temperature setback is well applied. Applying a feedforward is promising to improve its target response whereas its proper setting is required. In this paper, a two-degree of freedom control combining auto-tuning feed-forward and feedback was suggested for the control strategy. Simulation was then used to evaluate its performance compared to three conventional control strategies. Simulation results showed the two-degree of freedom control improved followability to the change of a target value by 30% compared to the proportionalintegral control. In conclusion, room temperature control is able to be improved by simple way without initial nor periodical tuning by service engineers.
