| 摘 要： | 研究了混合H2/H∞参数辨识问题.将混合H2/H∞估计方法应用到系统参数辨识中,给出了混合H2/H∞参数辨识算法.所得的算法不仅能满足规定的鲁棒性能,且为最小二乘(LS)参数估计误差判据提供了一个最优上界.结果表明:提高辨识的鲁棒性,需要牺牲辨识的精度作为代价.最后,仿真结果也验证了该方法的有效性.

| Abstract: | The paper studies the problem of mixed H-two/H-infinity parameter identification. The mixed H-two/H-infinity estimation method was applied to parameter identification of systems. The algorithm of mixed H-two/H-infinity parameter identification was presented, which was not only guaranteed to satisfy a pre-specified level of robustness, and also provides an optimized upper bound on the least-squares parameter estimation error criterion. The results showed that improving robustness of identification needs to be at the cost of approximation accuracy of identification. Finally, it was also demonstrated, via an example, that the proposed method is effective. |
