Abstract :
A new method of obtaining q-Markov cover models for linear discrete systems based on singular perturbation technique is proposed. The reduced-order models obtained not only match initial Markov parameters and high-frequency power moments like conventional q-Markov covers, but also match the initial time moments and low-frequency power moments of the original system
