An optimal algorithm of a system with dead time based on chaos and clone

The system with dead time is difficulty to control and is a significant focus in industrial control field. Twice optimum control (TOC) is one of competent control techniques for pure time-delay system. The method of TOC contributes unique performance employing the evaluation standard of integral time and absolute value of error (ITAE). The presented method of control optimization for pure time-delay system involves time-dividing model and parameters optimizing in two stages. The clone and chaos based algorithms are established for optimizing the time-delay system performance. The control system is configured for robustness and short step response time. The simulation results verify that the optimal algorithm is efficiency and accuracy.
