摘要
冗余输入系统在工程中占有重要地位,但是以前的研究主要集中在对控制分配问题的探讨上。从3个方面详细地讨论了多冗余控制输入在卫星运载火箭系统中的作用:二次型最优控制,H2控制和跟踪控制。发现能够通过增加控制输入使得系统的性能指标严格下降。但是,有些控制输入对系统性能指标的作用十分有限,从这个角度来看,一些控制输入是可以去掉的。
Redundant control inputs systems play an important part in engineering,but the previous researches on these systems mainly focuses on control allocation.The effects of the multiple control inputs in the satellite launch vehicle(SLV) system are researched in detail from three aspects: quadratic performance optimal control,H2 control and tracking control.It is found that the system performance index can be strictly decreased by increasing the control inputs.But the effects of some control inputs are very minor.From this point of view,some control inputs may be removed.
