Abstract

We propose a digital redesign method for plants with input time delay. When a network system is controlled, it is necessary to take into account the time-delay, and to keep the system stable. In this paper, we use the digital redesign and Internal Model Control (IMC). The system is able to compensate input time delay, input side disturbance, and to maintain the stability by combining IMC and input time delay using digital redesign. We confirmed superior performance by simulation study.
