Abstract:The operating principles of the INSb magnetic resistor are analyzed. The semi-bridge magnetic resistor can be used to measure the rotating velocity and displacement by biasing magnetic field acted on it. As the semi-conductor is sensitive to the temperature, a method to use the shifting zero-point to test the rotating velocity of the gear made from magnetic material is presented. And its features are also discussed.

Abstract:In this paper, the active vibration control for highly flexible cantilever under the impact force is studied by using the PZT as actuators and the independent mode control method, and the active control experiment is performed about the three mode vibration of the flexible beam. The experiment results show that the vibration of flexible cantilever beam can be effectively suppressed by using the independent mode control method. Using the mode filter to separate the vibration mode and phrase controller to adjust the phase of mode response, the greatest damping of the flexible beam and the excellent vibration control effect can be obtained.

Abstract:A new method is proposed to develop a test system about a kind of automatic pilot. With the help of Real-Time Windows Target Toolbox in MATLAB. operating on PC cards is very simple. Using the components like data acquisition cards basing on SimuLink Toolbox of MATLAB,a real-time simulink model can be built easily. A graphic user interface is developed with the GUI tool in MAT-LAB. When developing a test system, in addition to using the advantage in computing and displaying of MATLAB, operating on hardware is also supported. The final result validates the feasibility and facility of this method.
