PI controllers have been commonly used in air-conditioning systems. Among PID controllers, the D action is frequently switched off for the simple reason that it is difficult to tune properly. In some situations, it is possible to estimate thermal loads (or disturbances) before they will enter the plant. It is then natural to offset the thermal loads before they affect the control output. A typical...
Interacting systems between room air temperature of a single zone space and supply air temperature controls are considered. In air conditioning systems, the control loop can easily get into huntings. Variable air volume (VAV) control is very common for air distribution in air conditioning system today. Such interactions are assumed to be essentially to the source of huntings. To explore the possible...
