This paper presents temperature control and estimation using full state feedback controller with observer mechanism (FSFBCOM) in data centre. The temperature dynamic of a data centre was obtained in the form of transfer function and transformed into state space model. The system was initially modelled in MATLAB as an open loop system and simulation test was conducted to study the temperature characteristic performance of data centre without controller. The transient and steady state performance was presented in terms of time domain parameters: rise time, settling time, percentage overshoot, final value, and steady state error. The simulation result of the open loop system indicated a rise time of 1.41 min. (84.8 s), percentage overshoot of 0%, settling time of 2.68 min. (161 s), and final value to unit input is 10 °C, and steady state error of -9 °C. Simulation conducted when the designed FSFBCOM was introduced into the system showed that the performance parameters: rise time, percentage overshoot, settling time, final value, and steady state error became 0.41 min. (24.456 s), 0.232%, 0.8594 min. (51.564 s), 1 °C, and 0 °C respectively. Thus, the addition of the designed controller has improved the computer room temperature response performance of data-centre and provided good temperature estimation capacity even for different temperature values required of a data-centre.

This paper presents temperature control and estimation using full state feedback controller with observer mechanism (FSFBCOM) in data centre. The temperature dynamic of a data centre was obtained in the form of transfer function and transformed into state space model. The system was initially modelled in MATLAB as an open loop system and simulation test was conducted to study the temperature characteristic performance of data centre without controller. The transient and steady state performance was presented in terms of time domain parameters: rise time, settling time, percentage overshoot, final value, and steady state error. The simulation result of the open loop system indicated a rise time of 1.41 min. (84.8 s), percentage overshoot of 0%, settling time of 2.68 min. (161 s), and final value to unit input is 10 °C, and steady state error of -9 °C. Simulation conducted when the designed FSFBCOM was introduced into the system showed that the performance parameters: rise time, percentage overshoot, settling time, final value, and steady state error became 0.41 min. (24.456 s), 0.232%, 0.8594 min. (51.564 s), 1 °C, and 0 °C respectively. Thus, the addition of the designed controller has improved the computer room temperature response performance of data-centre and provided good temperature estimation capacity even for different temperature values required of a data-centre.
