Abstract

Time series files are the first available data about the control system. Actually, for the univariate loop we have available four variables: process output, manipulating variable, setpoint and control error. Analysis of this data in time domain is often the first shot in the CPA analysis. Once the time trends are properly acquired from the industrial system and delivered to the analysis, one can start playing with them. Step response and the associated indexes are almost always considered as the starting point. The main measures of the settling time and overshoot constitute the reference factors delivering commonly understood research and practical baseline. They are sometimes followed by their derivative indexes, which are based not only on the step loop response but also on the loop disturbance step or impulse response. This chapter puts together and summarizes the approaches that use time-domain step response as the fundamental element.
