The Robustness Analyses for Discrete Time Model Reference Adaptive Control System
离散时域模型参考自适应方案对建模误差的鲁棒性分析

In this paper, Narendra's discrete time model reference adaptive control scheme is analysed for its robustness to modelling errors. It is proved that this scheme is robust to type I modelling error and is not robust to type II modelling error. Simulation results are given to verify the above conclusions. Because of the unification of various model reference adaptive control schemes, the above conclusions possess generality.
