  • Abstract
    A frequency-limited interval Gramians-based balanced model reduction technique for discrete-time systems is proposed. The technique provides stable models and also yields frequency-response error bounds. Numerical examples are also presented. The results are comparable with other existing frequency-limited interval Gramians-based model reduction techniques.
