This paper develops an adaptive algorithm for position control of electrohydraulic servo
systems (EHS), with the objective of addressing variations in supply pressure. Most
approaches for control of EHS assume constant supply pressures, which in practical terms
require the use of additional components such as accumulators. In this article, we consider a
nonlinear model of an electrohydraulic system, establish a controller structure using
feedback linearization (model inversion) and then derive an adaptive control law for position …
