Adaptive Control of Electrohyadraulic Nonlinear Systems Using Nonlinear Reference Model

A new implementation of adaptive model following control (AMFC) scheme for electrohydraulic nonlinear systems by using nonlinear reference models is presented. The design of the nonlinear reference models which held the main nonlinearities of the controlled plants , and the linearization of the nonliaear models by using affine transformations and nonlinear state feedback transformations are discussed. Analysis and simulations show that the output of the reference model can be followed exactly by the controlled plant when using the proposed AMFC scheme.
