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.Abstract: 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.
