摘要
本文提出了通过构造与受控对象具有相同非线性特性的参考模型 ,并借助仿射变换和非线性反馈使参考模型线性化来实现对电液非线性仿射系统的模型跟随自适应控制方法 。
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.
