| Abstract: | The vibration fault detection approach for liquid propellant rocket engine is proposed based on quantum hypersphere neural network. The variable quantum hypersphere is used to mark work mode of engine, which provides probability amplitude that reflects the fault level. The off-line learning algorithm can extract engine vibration knowledge from training samples automatically. The monitor algorithm can forecast fault correctly, also learn new vibration information online. The analysis result of test data show... |
