摘要：

The precision motion stage exists the non-smooth nonlinear dead-zone varying with displacement and saturation simultaneously. In order to accurately describe such an electromechanical motion system, a novel Hammerstein-Wiener system (HWS) is firstly introduced to handle two non-smooth nonlinearities in this paper. Then, a three-step identification scheme based on two separable input signals is presented to estimate the parameters of HWS. Finally, the experimental results obtained by implementing the proposed identification scheme are also presented in this paper.
