Embodiment

[0058] The control computer can control the anti-backlash mechanism through fixed address injection, and the fixed address injection information involved includes:

[0059]

[0060] (1) The anti-backlash mechanism is positively locked

[0061] a) Control method

[0062] The requirements for the use of the anti-backlash mechanism are: when the anti-backlash mechanism is connected to the mechanism and locked in the forward direction, it will be driven at a frequency of 200Hz at the first gear. Under normal circumstances, it will run to Lock switch position.

[0063] If it detects that the locking Hall output signal changes from high to low within 50,000 steps of forward running, it will continue to move forward for 1,000 steps;

[0064] If the locking Hall output signal is still high after 50,000 steps of forward running, it will be driven forward with the second gear current at 200Hz frequency. If the locking hall output signal becomes low within 20000 steps, then continue t

Abstract

The invention relates to an anti-backlash locking mechanism driving control method and system for a spacecraft, and the method comprises the steps: adjusting the driving current of the stepping motor of the anti-backlash locking mechanism in a forward locking mode and a reverse unlocking mode, so that in a forward locking task, the driving torque of the anti-backlash locking mechanism is not larger than the torque during reverse unlocking all the time, locking of the mechanism during operation can be effectively avoided, and the feasibility of the method is verified through test results of special tests.
