请教各位专家一个问题：
通过自适应律的设计来消除参数不确定带来影响，通过反步控制的设计消除外部扰动。
我翻译成：
An adaptive law is introduced to reduce the parameter uncertainty and a backstepping control is adopted to eliminate the external disturbance.
这里我用and 来并列，感觉读起来不太舒服，有没更好的办法。谢谢!
通过自适应律的设计来消除参数不确定带来影响，通过反步控制的设计消除外部扰动。
参考译文：The influence brought about by parameter uncertainty is eliminated by the design of adaptive law,while the external disturbance is eliminated by the design of backstepping control .
参考译文:The design of adaptive law is employed to eliminated the effect/influence caused by the parameter uncertainty, while the design of backstepping control is employed to eliminated the external disturbance.
参考译文:The adaptive law is designed to eliminated the effect/influence resulted in/caused/brought about by the parameter uncertainty, while the backstepping control is design to eliminate the external disturbance.
