Short Review on Controller Design Approaches of Heating Ventilation Air Conditioner Systems Towards Energy-Efficient Buildings

The paper gives an overview of heating, ventilation and air-conditioning (HVAC) system and controller design approaches towards energy-efficient. The controller design approaches for the HVAC system can be categorized into the 3 main classes, which are the classical control approach, modern control approach and artificial intelligence control approach. Each category consists of different type of controllers which are presented. In classical controller approaches ‘ON’ and ‘OFF’ or PID controllers are the most significant influence to control the HVAC system whereas the modern control approach is used to reduce the weakness of the classical control approach. The artificial control approach is used to multi-criteria objectives of thermal comfort and energy saving without any need to mathematically model the system. The characteristics, as well as the advantage and limitation for each strategy are presented
