| 摘 要： | 本文研究了全系数自适应控制方法对未建模动态和有界干扰的鲁棒稳定性。证明了存在未建模动态及有界扰动情况下，采用经投影修正的梯度算法估计标称对象，黄金分割自适应控制器仍能稳定标称对象。对含乘性不确定性的线性定常对象，给出了自适应控制系统鲁棒稳定的充分条件。

| Abstract: | The robust stability of the all-coefficient adaptive control method with respect to unmodeled dynamics and bounded disturbances is studied in the paper. It is proved that in the presence of unmodeled dynamics and bounded disturbances, the golden section adaptive controller still can stabilize a nominal plant when a gradient update law modified by parameter projection is used to estimate the nominal plant. A suffiient condition is presented for linear invariant systems with multplicative uncertainty. |
