| Abstract: | This study tries to avoid the influence of time-delay variation on the stability of the closed-loop system by choosing an apposite sampling time and closed-loop system time constant. There by a concept "Dahlin Algorithm Absolute Stability" is presented. Two necessary conditions and two sufficient conditions are obtained by using July stability criterion in the Dah-lin Algorithm digital control system. These conditions are of theoretical and practical significance for the design of digital control systems with better robustness. |
