In this paper, we address two issues: digital redesign of a continuous-time system with an input time delay, and to translate the pulse-amplitude modulated (PAM) controller obtained by the newly proposed digital redesign method into an equivalent pulse-width modulated (PWM) controller. A tuning parameter is introduced into the PAM controller so that the digitally controlled sampled-data states closely match with the original continuous-time input time-delay states. Also, the principle of equivalent areas is applied to convert the newly developed PAM controller to an equivalent PWM controller so that the PWM controlled states closely match with the PAM controlled states for a relatively longer sampling period.
