深研院宣(文/戚文念 图/张一阳)11月21日下午4:00,应机电工程与自动化学院吴爱国教授邀请,西悉尼大学郑维行教授在A503为我院师生做了一场题为“Nonparametric Identification of Nonlinear Autoregressive Systems with Exogenous Inputs”的学术讲座。讲座由吴爱国教授主持,控制工程学科部分博士、硕士研究生参加了此次学术讲座。

讲座中,郑维行教授首先简单地介绍了线性系统参数辨识的基本概念和发展历史。随后,郑维行教授由线性系统过渡到非线性系统,详细的讲解了外源输入非线性自回归系统及其非参数辨识的基本概念,阐明了非参数辨识并不是辨识出非线性函数的具体参数,而是在相关特定点出给出非线性函数的函数值,介绍了针对有关非线性系统已有的辨识方法,包括直接权重优化法、核方法以及局部线性估计方法(LLE)。并且重点围绕递归局部线性估计方法(RLLE)进行了讲解,给出递归局部线性估计算法的具体形式,并且对此算法的收敛性、强一致性和均方误差性能进行分析。

最后,郑维行教授给出了该算法的仿真实例,证明了此算法的优越性,并指出了后续的研究方向。

讲座结束后,现场师生就讲座中的相关内容进行了深入交流与探讨。   

郑维行教授简介:

Wei Xing Zheng received the B.Sc. degree in Applied Mathematics in 1982, the M.Sc. degree in Control Theory and Applications in 1984, and the PhD degree in Control Theory and Applications in 1989, all from Southeast University, Nanjing, China. Over the years, he has held various faculty/research/visiting positions at Southeast University, China; Imperial College of Science, Technology and Medicine, UK; University of Western Australia, Curtin University of Technology, Australia; Munich University of Technology, Germany; University of Virginia, USA; and University of California-Davis, USA. Currently he holds the rank of Full Professor at University of Western Sydney, Australia. Dr. Zheng is a Fellow of IEEE and a Thomson Reuters Highly Cited Researcher. Previously, he served as an Associate Editor for IEEE Transactions on Circuits and Systems-I: Fundamental Theory and Applications, IEEE Transactions on Automatic Control, IEEE Signal Processing Letters, IEEE Transactions on Circuits and Systems-II: Express Briefs, and IEEE Transactions on Fuzzy Systems, and as a Guest Editor for IEEE Transactions on Circuits and Systems-I: Regular Papers. Currently, he is an Associate Editor for Automatica, IEEE Transactions on Automatic Control (the second term), IEEE Transactions on Cybernetics, IEEE Transactions on Neural Networks and Learning Systems, and other scholarly journals.
