Mean‐Square Approximate Systems and Their Application in Estimating Response in Complex Disordered Linear Systems

摘要: A new method is presented for predicting approximately the response in complex, lightly damped, disordered linear systems to transient or steady‐state disturbances when frequency content of disturbance a band involving high natural frequencies undamped system. The consists constructing sequences coupled oscillators that derive from system description by minimizing mean‐frequency weighted function coordinates subject suitable constraints.
