Abstract: PPI controller parameters are usually set by adopting trail-and-error or parameter setting method to setting.It is hard to give consideration to various targets.This paper presents a kind of data visualized setting method based on steady settings, that is, using the frequency and time domain performance index to optimize its parameters and transforming the PI controller phase angle and amplitude margin mathematical models into frequency response information of controlled objects for drawing up the graph, then the intersection of which can orderly meet the frequency domain and time domain steady solutions.The step response verifies the effects of this data visualization method.
