Filed: 1983-12-02
Abstract: PURPOSE:To enhance the servo rigidity of a control apparatus by erasing the fold point of a major rate loop and stably enhancing a tracking position gain, by directly adding the output of a gyro-torque to a minor rate loop. CONSTITUTION:When a certain gain is imparted to the output of an angular error detector by a discriminating gain 21, the output thereof receives the subtraction of the angle signal (c) of a control object through a gyro-torque gain 22 and inputs the subtracted output to an integration gyro 23 while the output of the gain 22 is directly added to a minor rate loop. Therefore, the fold point of the major rate loop is erased and tracking position gain is stably enhanced and the servo rigidity of a control apparatus can be enhanced.
