As an application of fuzzy control technologies, a refrigerant flow control of package airconditioners has been thus far established. But, it is difficult to control refrigerant flow precisely by the conventional technologies, because package airconditioners have various operational environments, such as, machine type, length of refrigerant pipe and so On. Therefore, for high quality control, it is important to design controllers such that they can adapt to these varying environments. In that respect, we have established a new controller which has cascade two layer structure of fuzzy controller, in order to achieve higher refrigerating capacity. Adaptability problem is, however, not still enough solved in this controller. In this paper we report the above controller and two additional attempts which add farther adaptability to the controller. We first outline the controller which has cascade two layer structure of fuzzy controller. Then, we improve the controller, in order to make fit for practical USe. Finally, we develop a new automatic tuning method for fuzzy control that uses a look up table, in order to improve stability. We demonstrate the desired ability of the new controller by experiments and simulation.
