Investigation on PID Controller Tuning Methods for Aircraft Fuselage Temperature Control

Aircraft cabin temperature control is crucial in maintaining constant temperature inside the aircraft flying at high altitudes. In such altitudes, the atmospheric temperature and oxygen availability are very low in contrast to the requirements inside the aircraft. For constant monitoring and maintenance of temperature in real-time, the controller should be highly sensitive to parameter variations and hence require lower processing times for quick response. Traditional control method such as PID control offer faster response with lower computational overhead. In this work, model of aircraft temperature control system with PID controller is considered and different methods of finding the controller’s coefficients are presented. The comparison of methods is done and recommendations are made based on parameters such as overshoot, settling time and stability
