The invention provides an optimized driving control and positioning method for an anti-backlash locking mechanism for a spacecraft, and the method comprises two closed-loop modes: the first closed-loop mode is used for enabling the anti-backlash locking mechanism to operate to a locking working position; and the second closed-loop mode is used for operating the anti-backlash locking mechanism from the locking working position to the suspension working position. The method can be used for five working conditions, four working conditions are switching among working positions, and the other working condition is zero searching positioning after the computer resets the lost step number. Meanwhile, the two closed-loop modes designed by the invention both comprise accurate positioning strategies, so that the optimized driving control and positioning of the anti-backlash locking mechanism are realized, and when the anti-backlash locking mechanism runs to a contact working position, the influence caused by stroke blocking and motor step loss is overcome.
本发明提供一种空间航天器用消隙锁紧机构优化驱动控制及定位方法,包含两个闭环模式,第一闭环模式用于消隙锁紧机构运行至锁紧工作位置;第二闭环模式用于消隙锁紧机构从锁紧工作位置运行至悬浮工作位置。本发明可用于5种工况,其中四种工况为各工作位置间的切换,另一种工况为计算机复位丢失步数后的“寻零”定位。同时,本发明设计的两个闭环模式均包含精确的定位策略,实现了对消隙锁紧机构的优化驱动控制及定位,并在消隙锁紧机构运行到接触工作位置时,克服由于行程受阻,电机丢步造成的影响。
