Abstract
This paper considers the design method of discrete equivalents of analog controllers. A new design method for discrete equivalents of analog controllers is proposed. The proposed design method is an improved pre-warped bilinear transformation and is simple. The resulting digital controller does not have any extra phase-lag compared with the original analog controller in a frequency range under the maximum absolute value of poles and zeros of the analog controller, even when it is lower but comparable with the Nyquist frequency
