A frequency response identification method for discrete-time processes with cyclic steady state conditions

Abstract: A new frequency response identification method is presented to estimate frequency responses of discrete-time processes. It provides exact frequency response data sets for any desired frequency. This method incorporates various process signal types such as both initial and final steady state, initial steady state and final cyclic steady state and both initial and final cyclic steady state. Also, the proposed algorithm completely removes the effect of static disturbances and it shows acceptable robustness to measurement noises.
