摘　　要：本文分析了Narendra的离散时域模型参考自适应控制(DTMRAC)方案对建模误差的鲁棒性,证明该类方案对Ⅰ型建模误差的鲁棒性较强,对Ⅱ型建模误差的鲁棒性差。仿真结果证明了鲁棒性的分析结论。由于模型参考自适应诸方案有统一性,上述结论也具有普遍性,并对模型参考自适应方案在计算机控制系统中的应用具有指导意义。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 vatious model reference adaptive control schemes, the above conclusions possess generality.
