| 摘 要： | 将单输入单输出非最小相位离散时间系统的模型参考自适应控制的新方法（即用从最小二乘获得的近似逆系统方法）推广到多变量场合．讨论了如何避免不稳定的零极点对消及如何将扰动的作用与对象的输出进行解耦的问题．计算机仿真结果说明了推广方法的有效性．

| Abstract: | A new method, or one using approximate inverse systems obtained from the least square method, is used to extend the model reference adaptive control with single input and single output for nonminimum phase discrete time systems to the multivariable case. It is shown that the unstable pole zero cancellation can be avoided and disturbances can be decoupled from the output of the object. The effectiveness of the generalization is verified by computer simulation. |
