The invention discloses a fault-tolerant method for a full authority control system of a turbofan engine. The fault-tolerant method for the full authority control system of the turbofan engine includes the following steps that (1) the full authority electronic-control control system receives signals transmitted by all sensors on the turbofan engine; (2) whether the signals transmitted by the sensors break down or not is judged, the steps are stopped if the signals transmitted by the sensors do not break down, and the next step is executed if the signals transmitted by the sensors break down; (3) the types of faults occurring in the step (2) are judged; and (4) a fault-tolerant solution method used when the types of faults stored in the full authority electronic-control control system occur are called, and the fault-tolerant solution method is executed. According to the fault-tolerant method for the full authority control system of the turbofan engine, when the faults of the sensor signals such as the rotating speed and the temperature occur in the control system, recombination and optimizing of a control system structure and a control system plan are achieved, and the working reliability of the control system is greatly improved.
Description
technical field [0001] The invention relates to the technical field of turbofan engine control, in particular to a fault-tolerant method for a full-authority control system of a turbofan engine and a fault-tolerant system for a full-authority control system of a turbofan engine. Background technique [0002] Fault-tolerant control technology means that when some components fail and the original control plan cannot be realized, the control system automatically adjusts the control plan and control structure to ensure that the engine can still complete the engine safely according to the original performance or a slight decrease in performance. A technique for a given control task. Using the powerful calculation ability, logical judgment ability and decision-making ability of modern computers, good results have been achieved in improving engine reliability and maintainability. Due to the limited comprehensive parameters of the original mechanical-hydraulic control system, no ma...
