摘要: 本文研究了具有混合自适应律的直接型模型参考自适应控制.对这种混合的MRAC方 案,我们严格地证明了闭环系统的所有信号都有界,同时得到了跟踪误差满足e1∈S(μ2(△2+ △2∞)+d20+1/a20).同文献[1]的控制方案相比,这种具有混合自适应律的直接型模型参考自适应 控制具有如下优点:1)实现过程中计算量大大减小;2)具有更好的鲁棒性.

Abstract: Direct model reference adaptive control (MRAC) with hybrid adaptive law is studied in this paper. For the hybrid MRAC scheme, we prove rigorously that all signals in the closed-loop system are bounded, meanwhile the tracking error satisfies e1∈S(μ2(△2+△2/∞)+d2/0+1/a2/0) Compared with control schemes in [1], the hybrid MRAC has the following advantages: (1) the smaller computational effort during implementation, and (2) the better robustness properties in the presence of measurement noise.-
