【摘要】：針對(duì)具有參數(shù)不確定航天器大角度姿態(tài)機(jī)動(dòng)的非線性控制問題,提出一種分散保性能控制律。研究剛性航天器大角度機(jī)動(dòng)中航天器姿態(tài)控制問題時(shí),忽略撓性模態(tài)對(duì)其的影響。在對(duì)具有參數(shù)不確定航天器進(jìn)行建模的前提下,對(duì)模型的性質(zhì)進(jìn)行了描述。利用反饋線性化方法將航天器姿態(tài)動(dòng)力學(xué)模型變換成三個(gè)部分進(jìn)行分散控制器的綜合,設(shè)計(jì)保性能控制律對(duì)航天器模型中參數(shù)不確定性進(jìn)行抑制。由于引入保性能控制律,在補(bǔ)償參數(shù)不確定性的同時(shí)還能夠滿足系統(tǒng)性能指標(biāo)的要求。仿真實(shí)驗(yàn)結(jié)果表明,所設(shè)計(jì)的控制律能保證航天器在不確定性的影響下,精確完成大角度姿態(tài)機(jī)動(dòng),驗(yàn)證了方法的有效性。
[Abstract]:A decentralized guaranteed cost control law is proposed for nonlinear control of large angle attitude maneuver of spacecraft with uncertain parameters.In the study of attitude control of rigid spacecraft in large angle maneuvering, the effect of flexible mode on attitude control is ignored.On the premise of modeling the spacecraft with uncertain parameters, the properties of the model are described.The attitude dynamics model of spacecraft is transformed into three parts by feedback linearization method to synthesize the decentralized controller. The guaranteed cost control law is designed to suppress the uncertainty of parameters in the spacecraft model.Due to the introduction of guaranteed cost control law, it can compensate the uncertainty of parameters and meet the requirement of system performance index.The simulation results show that the proposed control law can guarantee the spacecraft maneuvering at large angle under the influence of uncertainty, and the effectiveness of the method is verified.
