针对分数阶航天器刚体姿态运动系统,首先根据航天姿态动力系统的分数阶特性,提出了系统的分数阶模型,并运用Adomian分解法对其进行求解与混沌特性仿真;其次运用简单的单向耦合同步策略,设计出了同量分数阶航天姿态动力系统的同步控制器;最后通过仿真验证了所提出的控制策略.仿真结果表明了所提出同步控制器的可实现以及有效性.
According to the fractional order characteristics of aerospace attitude dynamical system, a fractional order model of the system is proposed for the fractional spacecraft rigid body attitude moving system. Adomian decomposition method is used to solve the problem and chaotic characteristic simulation. Secondly, a simple unidirectional coupling Synchronization strategy, a synchronization controller with the same amount of fractional order aerospace attitude dynamic system is designed. Finally, the proposed control strategy is verified by simulation. The simulation results show that the proposed synchronization controller can be realized and effective.
