Abstract: Most of the controllers commissioned in industrial areas are of Proportional-integralderivative (PID) type. Tuning a proper PID controller requires an accurate model of a Process and an effective controller design rule. The tuning procedure can be a timeconsuming, expensive and difficult task. This is also true to Heating, Ventilating, and Air-conditioning (HVAC) systems. Although many improved PID design methods are proposed, the Ziegler and Nichols (Z-N) methods are still adopted by many HVAC control engineers. The Z-N methods have been most commonly used in HVAC systems. It has sometimes been difficult to compensate fully for load disturbance and to keep controlled variables close to set point values within the prescribed range, have the shortcomings such as long testing time, limited control performance.
