摘　　要：针对具有噪声的多变量系统,利用高频增益矩阵K。_p=S_1D_1U_1分解,提出了一种多变量鲁棒直接型模型参考自适应控制．通过重新证明一些同单变量系统鲁棒自适应控制理论相似的性质,及重新定义规范化信号,找出了闭环系统的所有信号与规范化信号之间的关系,严格地分析了闭环系统的稳定性和鲁棒性．For multivariable systems with disturbances, by using high frequency gain matrix Kp=S1D1U1 factorization, a multivariable robust direct model reference adaptive control is provided in this paper. Firstly, some similar properties to robust adaptive control theory for SISO systems are proved, and the normalizing signal is redefined. The relationship between all the signals in the closed-loop system and the normalizing signal is then established. Finally, the stability and robustness of the closed-loop system are analyzed rigorously.
