AB - Primitive controllers used in the early version for HVAC systems, like the  on-off (Bang-Bang) controller, are inefficient, inaccurate, unstable, and  suffer from high-level mechanical wear. On the other hand, other controllers  like PI and cascade controllers, overcome these disadvantages but when an  offset response (inaccurate response) occurs, power consumption will  increase. In order to acquire better performance in the central  air-conditioning system, PIP-cascade control is investigated in this paper  and compared to the traditional PI and PID, in simulation of experimental  data. The output of the system is predicted through disturbances. Based on  the mathematical model of air-conditioning space, the simulations in this  paper have found that the PIP-cascade controller has the capability of  self-adapting to system changes and results in faster response and better  performance.
