In noise robust speech recognition, for PMC(parallel model combination) method, the performance of the combined model can approach that of the model matching the noisy environment theoretically, so it is an important noise robust speech recognition research field.

Research on The Noise Robustness of Speaker Verification System Based on Sub-band HMM/MLP Model;

A method of noise robust speech recognition is investigated by combining a blind source separation algorithm and MFCC(Mel-Frequency Cepstral Coefficients).

Dyeing control based on robust H_∞ multi-step prediction;

Parameter tuning for nonlinear robust controller with high gain observer;

Designing method of robust dynamic inversion for 3-D terminal guidance law;

The iterative learning control of a class of nonlinear system with the robustness of initial state;

It can obtain some good and bad points of these two methods separately according to aspects such as forecasting accuracy rate,the speed,robustness,understanding easily and so on with the concrete instance data.

To our best knowledge,the only multivariable design method in the open literature that can optimize robustness is μ synthesis method,which we utilize to add optimal robustness to good command response of aircraft longitudinal control system.
