The basic principles and structure of the 2.1 active servo feedback
Active servo feedback technology to expand the low-frequency characteristics of the pick-up device,the basic principle is to use active servo feedback technology to increase the quality of the pendulum system,to achieve the purpose of reducing system natural frequency.Sensor principle shown in Figure 2,X is the measured object relative to the displacement of the inertial reference system (Earth),called the absolute displacement; x is the pendulum relative to the displacement of the measured object,called the relative displacement; k spring stiffness; b for the system damping; m is the quality of the pendulum; G1,the main coil electromechanical coupling constant; G2 electromechanical coupling constant of the feedback coil; i is the current into the feedback loop; R is the load resistance; K magnification; the KD (1 + TDs,) for the proportion of differential link.
