Convergence rate and stability of adaptive filter with state-space feedback contorller for active micro vibration contolr

摘要

In this paper,we wil show htat the feeback controller in this hybrid contolr technique increases the ocnverence rate and the stability of adaptive filter.To show theswe effects of feedback controler,the correlation matrix of the filtered referene singal in the filtered-x LMS algorihtm has bne einvestigated.The analysis revealed tha twe cna take the significant imporvemnt in eigenvalues spread performance by uing hybrid control strategy.
