| 摘 要： | 空间载人机动装置(MMU)在进行救援过程中,其动力学参数存在很大的不确定性.为解决这一辨识问题,本文首先推导系统关于各动力学参数的线性化模型,然后结合该线性模型的特点,提出了一种用于估计动力学参数的改进鲁棒投影算法,并在理论上分析了该算法的收敛性质,数字仿真验证了方法的有效性.

| Abstract: | Since system dynamic parameters of manned maneuvering unit(MMU) may change abruptly,the identification error is usually large.In order to solve this problem,an improved robust projection identification algorithm is proposed based on the linearization model and the convergence is analyzed.Finally,a simulation on an MMU is carried out to verify the effectiveness of the proposed approach. |
