POSITIVE-DISPLACEMENT HYDRAULIC DRIVE WITH POSITIVE FEEDBACK WITH RESPECT TO THE PRESSURE DIFFERENTIAL IN THE HYDRAULIC MOTOR WITH THE PRESENCE OF LONG LINES

摘要

We describe a method for studying the stability of a hydraulic drive with and without positive feedback. The method is verified experimentally and by simulation modeling. It is shown that by tracking the control signal we can study the stability of the linear and nonlinear systems by the frequency technique. The influence of the wave processes is evaluated using a graph that is presented in the paper.
