Abstract: A concept of dual-redundant control law design for aero-engine was proposed and a method of utilizing dual-redundant control law for the control sensors signal fault processing policy was derived in the paper.The technique and principles of the backup control law design were built and applied to the dual-redundant control law design and research of one high performance turbofan engine.The study result indicates that the dual-redundant control law can be made undisturbed conversion and control loop reconfiguration,so that mission reliability of engine is improved.The means may have application in all kinds of engine which is equipped with digital electronic control system.
