PROBLEM TO BE SOLVED: To characterize a frequency response of a new and improved multirate system.;SOLUTION: Frequency response is characterized for mechanical components of a multirate system operating in a closed-loop environment. A disturbance is injected at the frequency of interest and at each of alias frequencies thereof as an input into the multirate system (step 503), and a matrix equation composed of resulting measurements of the response of the multirate system is solved to compute the frequency response at the frequency of interest and at each of the alias frequencies (step 506). The resulting frequency response is used to synthesize the transfer function of the entire system, which allows simulation and evaluation of the relative performance of multiple controller designs without the need for further frequency response measurements.;COPYRIGHT: (C)2010,JPO&INPIT
