Mixed H/H parameter identification
混合H2/H∞参数辨识

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.
