Embodiment Construction
[0007] The specific embodiment of the present invention is as figure 1 As shown, let the control amount of the first DC torque motor be u 1 , the control amount of the second DC torque motor is u 2 , the differential amount Δu is the minimum control amount that can overcome the static friction of the transmission mechanism when the two motors independently drive the stable platform, take u 1 =u+Δu,u 2 =u-Δu, the control value u of the first DC torque motor 1 and the control variable u of the second DC torque motor 2 After passing through the first servo amplifier and the second servo amplifier, respectively, drive their respective DC torque motors. When |u|≥|Δu|, the first and second two DC torque motors drive the transmission gear in the same direction, and when |u|<|Δu|, the first and second two DC torque motors form a reverse drive The transmission gear, in which the DC torque motor with a large absolute value of the control amount plays a leading role in driving the r...
