Abstract :
This paper proposes a new performance index, called energy resemblance index (ERI), in the digital redesign for analog control systems. The ERI is defined as the ratio of the integral of square error of continuous-time system over the error sequence energy of the redesigned digital system. Performance of the redesigned digital control system using different discretization methods at different sampling times can be evaluated based on this index. If an ERI percentage is specified, proper sampling time can be determined so that the redesigned digital system performs accordingly
