用δ算子设计离散系统模型参考自适应控制的一种方法(英文)

A Design Method for Discrete-Time Model Reference Adaptive Control Using Delta Operator

提出用δ算子设计离散系统模型参考自适应控制的一种新方法 .该方法的特点是在闭环内控制器的设计中利用了离散对象的非主导模型 ,而在现有的方法中 ,非主导模型被当作动态模型干扰来处理 .仿真结果证实该方法对采样速率的要求比现有方法宽松 .

In this paper,a new method for the design of discrete-time indirect model reference adaptive control using delta-operator is presented.The nondominant part of the discrete-time model is included in the inner-loop controller design,rather than be treated as unmodeled dynamics.Simulation results verify that the proposed method can tolerant larger sampling period than existing methods.
