Experimental determination of dynamic parameters of a drying drum as an object of automatic control
Abstract
As is known, many objects (sites) of automatic control can be experimentally investigated by applying step or pulse inputs to the object, obtaining respectively the step or pulse response at the output. Determining the dynamic parameters of the object from its pulse response is preferable to the step response, because, firstly, it gives more accurate results and, secondly, conducting an experiment with the impact in the form of a pulse is less disruptive to the normal course of the technological process. When taking the dynamic characteristics by this method, the following is assumed: 1) all disturbing influences during the experiment can be stabilized within certain limits so that their influence on the output parameter can be neglected; 2) the pulse disturbance does not entail significant nonlinear distortions of the transient process.
