Method for determining parameters of controlled systems

摘要

In the method for determining controlled system parameters "delay time" and "compensation time" with the aid of the tangent at the turning point of a step response at the output of a higher-order controlled system, the tangent with the steepest gradient is determined by means of regression calculation over N measurement points, the points of intersection of which tangent with the time axis of the straight lines which are parallel to the time axis and correspond to the static end value bounding compensation time and delay time. The invention is used in the design of control circuits for processes and for producing process models. <IMAGE>
