摘　　要：　基于高频增益矩阵因子分解和Backstepping设计方法,对多变量MRAC系统设计出一种新的自适应控制器,改变了已有的研究中关于高频增益矩阵的假定条件.该控制器能保证系统的全局稳定性和跟踪误差趋于零.仿真效果也证明了所提算法的实用性.In this paper, a new adaptive control scheme is proposed for multivariable MRAC systems based on the high frequency gain matrix factorization and backstepping approach. The existed assumptions of the priori information about the high frequency matrix have been improved. This control scheme guarantees the global stability of the closed\|loop systems and makes the tracking error tend to zero. The simulation results illustrate the effectiveness of the proposed scheme.
