1. An inertial sensor control module, comprising:
at least one inertial sensor including a driving mass; a driving unit driving the driving mass of the inertial sensor according to a control signal to the inertial sensor; a control unit connected to the driving unit and generating a control signal to transfer the generated control signal to the driving unit; and a sensing unit connected between the inertial sensor and the control unit and detecting information about whether the driving mass of the inertial sensor is in a stabilized state to transfer the detected information to the control unit, wherein the sensing unit detects an amplitude peak value of the driving mass and delivers the detected amplitude peak value to the control unit, and wherein the control unit compares a difference value Δt between a target value T and the amplitude peak value P with a threshold value; when the difference value Δt between the target value T and the amplitude peak value P has a larger value than the threshold value, the control unit operates an AGC, calculates a gain, produces a control signal reflecting the calculated gain and applies it to the inertial sensor through the driving unit; and when the driving mass is in a stabilized state, operates the AGC again, calculates a new gain and applies the new calculated gain to the inertial sensor through the driving unit.
