P-Map: An Intuitive Plot to Visualize, Understand, and Compare Variable-Gain PI Controllers

摘要: This paper introduces P-map, an intuitive plot to visualize, understand and compare variable-gain PI controllers. The idea is represent the difference between a target controller baseline (or second for comparison) by equivalent proportional controller. By visualizing value of gain examining how it changes with inputs, possible qualitatively characteristics complex Examples demonstrate that P-map gives more useful information than control surface So, can be used supplement or even replace surface.
