DIGITAL CONTROL EXPERIMENT RESEARCH ON THE ENGINE JT15D-4

Studying digital control system is made on the engine JT15D-4 in this paper. It aims at both the design and real problem in running about digital control system. To improve the reliability of the system some measures are adopted, such as double-computer-linked communication, condition performance monitoring, hydraulically machanical prepared regulator, alarm lit by software fault diagnosis and so on.Through digital simulation, half-physical simulation test and real running on the engine test rig, it is verified that the structure and design of the system are correct and it is believed that the practical experience will be given to further research of the full-authority digital control.
