Abstract :
A mixed method of linear system model reduction, retaining the advantages of the power decomposition method and the frequency response matching method, is proposed. From the viewpoint of energy contributions to the system output, the dynamic modes with dominant energy contributions instead of those with dominant eigenvalues will be preserved. Having determined the denominator of the reduced model, the parameters of the numerator are found by using the frequency response matching technique.
