| description | The invention discloses an indirect driving high-precision servo implementation method under nonlinear interference, and belongs to the technical field of seeker stabilized platforms. The method can solve the problem that the servo performance becomes poor due to factors such as nonlinear interference torque, gear transmission backlash and friction torque caused by shaft penetrating cables, wherein the shaft penetrating cables adopted by the stabilized platform are in a spiral wiring mode. The method includes the following steps that an ideal system model of the stabilized platform is built and calibrated, so that a transfer function G0 of the ideal system model is obtained; a servo control algorithm is adopted to carry out servo control over the stabilized platform of the seeker; the angular velocity v of a frame is compared with the polarity of the output voltage u of a motor, and when the v is different from the u polarity, backlash compensation is superposed in the control quantitycalculated by the servo |
