| 摘 要： | 本文针对矩阵分解的多变量自适应控制，提出了具有噪声与未建模动态系统的鲁棒自适应控制问题.在高频增益矩阵分解的基础上，得到等价自适应控制律，通过重新定义虚拟规范化信号，对多变量的MRAC方案进行了理论分析，并证明了闭环系统的稳定性和收敛性.最后仿真验证了该方案是可行的.

| Abstract: | According to multivariable model reference adaptive control, the robust adaptive control problem for systems with noise and un-modeled dynamics is proposed. The certainty-equivalence adaptive control law is obtained through high-frequency gain matrix factorization. And multivariable MRAC scheme is analyzed by introducing the normalizing signal, moreover, the stability of closed-loop plant and convergence of error are proved in detail. Finally, the simulation results show that the scheme is effective. |
