摘要
A procedure for obtaining a proper rational approximant of the transfer function of a delayor is suggested. In particular, the step response of the unity-feedback system with the delayor in the direct path is first approximated by truncating the Fourier series expansion of its periodic component, and then the corresponding direct-path rational transfer function is derived, thus arriving at a stable Blaschke product.
