Aircraft electronic oxygen regulator (AEOR) is a new type of oxygen regulator which is the core of the Oxygen Supply System. At present, there is no good control method for the electronic oxygen regulator to meet the requirements of the existing technical index. By analyzing the principle of the AEOR, a new experimental research method of control system was designed for AEOR based on LabVIEW FPGA. Expert PID control rule was used and optimized to improve. The experiment result indicated that the AEOR control system was accurately performed and the control program had good response speed and control precision.
