Abstract

In this paper, we design a qualified proportional-integral-derivative (PID) controller for air-conditioning process. Two-degree freedom control structure is designed for decoupling the set-point following and attenuation of load disturbances. The optimization algorithms are used for guaranteeing enough ability to reject load disturbances to the robustness constraints. The control performance of typical tuning methods is often relatively poor although it is quite user-friendly. On the other hand, the controller designed by optimizing algorithms performs better while it is computationally expensive. The novel algorithm is designed to overcome this contradiction. The method based on genetic algorithm is convenient and practical. Finally, the humidity conditioning process experiment is used to prove the effectiveness of our method.
