黄金分割

Through the characteristic parameters, the system's real-time moment of inertia is given. Then golden section adaptive control law and logic derivative control law both based on moment of inertia are designed. The two kind of control laws are combined to control the attitude of spacecraft and their simulation results are compared with the ones of PD control law which is designed based on the certainly-known system model. The results show that this adaptive control law is effective on the kind of time-variable system studied in this paper.

根据特征模型的参数推算了系统实时的转动惯量，设计了基于转动惯量的黄金分割自适应控制器和逻辑微分控制器，将这两种控制器相结合对带有可伸缩挠性附件的刚体进行姿态控制，仿真结果与基于确知系统模型所设计的变系数PD控制器相对照，表明了该自适应方法控制一类时变系统的有效性。
