摘　　要：步进指向控制系统是先进空间光学遥感器的核心部件。在天基预警、空间光电对抗等领域有着广泛的军事应用需求,具有指向精度要求高,步进动态限定强等特点。提出一种基于主导极点配置的频域校正控制律设计方法,该方法有效建立了步进时域性能与频域校正指标间的联系,从而简化了控制律的设计难度。仿真试验验证了该方法的有效性。Step pointing control system is the main part of advance space optical remote sensor. It is widely used in space based early-warning system, electro-optical countermeasure of the space. It requires high precise and low overshoot of dynamic performance. A new method of based on dominant poles frequency domain correction con- troller designing is presented to deal with this problem. It effectively builds the relationship between temporal char- acteristics and parameters of frequency domain correction controllers, therefore the design of control law is simpli- fied. Computer simulation results show the effectiveness.
