Application Of Inverse System Method In Centrifugal Force And Vibration Compound Environment

The test simulating the centrifugal force and vibration compound environment is used comprehensively in engineering for it can forecast the potential fault that can't be found in single environment test, therefore it is possible to enhance the safeness of the system. In the process of simulating the compound environment ,in order to accomplish the expected environment or to eliminate the unexpected disturbance, it's inevitable to consider the vibration control.At first, by applying the inverse system theory, the inverse problem, namely load recognition, can be ascribed to establish the inverse system and solve directly the problem of the inverse system, then the end of load recognition is reached.Furthermore, the linear-coupling system is controlled with inverse system method. The inverse system is deduced and the hypocritical linear system is constructed, finally the original system is decoupledIn addition to what is mentioned above, the mathematics model of vibrator in centrifugal force and vibration compound environment is founded and the corresponding inverse system is deduced when displace, velocity and acceleration are respectively treated as control target. And the hypocritical linear system is formed by integrating the original system with inverse system, as a result the time-variety coupled system is decoupled and linearized.At last, two advanced researches about the inverse system method are mentioned. One is the application of inverse system method to the nonlinear random vibration. The other is to associate the inverse system method with the intelligence control. By taking the advantage that the neutral network can recognize the nonlinear system, the inverse system can be substituted approximately by trained neutral network. This ideal overcomes the defect of the difficulty of deducing the inverse system and further the research of the inverse system method.
