Abstract
Nonlinear effects such as asymmetric actuation, nonlinear transmission ratio, variations in the trapped fluid volume as well as nonlinear pressure/flow gains limit the performance of electrohydraulic servosystems under linear control. Using the dynamic inversion principal a globally linearizing feedback control law was developed and experimentally verified on an electrohydraulic system. The results indicate that better uniformity of response was achieved across a wider range of operating conditions and improved symmetry was obtained for the extension and retraction phases of motion. As a result of the improvement in the linearity, better performance is achieved with linear controllers.
