Estimating Critical Point Information in High Accuracy Based on the Modified Describing Function Analysis

摘要：

This paper proposed a derivation phase which leads to the remarkable improvement of identification accuracy for estimating the critical point in process control system over existing relay-based methods. The simulation experiments show the effectiveness of this method for the majority of all those with low- and high-order, small and large dead time, monotonic, and oscillatory responses processes.
