Abstract: Proposed is a method of delay identification for SISO linear plant. The plant is described by transfer function with unknown coefficients, has unknown delay and affected with unknown bounded disturbances. The identification method is based on the finite-frequency identification that uses test signal (polyharmonic function) to determine unknown plant transfer function coefficients and delay.

Keywords: frequency identification, time delay, lti-systems, bounded disturbance.
