Control Oriented System Identification: An H∞ Approach

A comprehensive, one-stop reference for new system modeling and identification tools The field of control-oriented identification has grown immensely over the past decade, spawning numerous results and modeling techniques and promising the potential to influence science and engineering for years to come. In this new work, Jie Chen and Guoxiang Gu, two leading authorities on worst-case identification, share their vision and walk readers through carefully selected topics from the vast literature, offering a much-needed, timely comprehensive introduction to the theory of H identification and model validation. Chen and Gu clearly demonstrate the pros and cons of the worst-case approach in comparison to traditional techniques and provide researchers in systems and control theory with ready access to many new and complementary identification tools. Through a rigorous yet logical and easy-to-follow treatment, supported by many deep insights, intuitions, and philosophical thinking, they: Survey and assess the current state of control and system identification research Develop both two-stage and interpolatory algorithms for system identification Show readers how to analyze the properties of linear algorithms Offer a unique emphasis on model uncertainty estimation and complexity, two of the central issues Develop both time-domain and frequency-domain identification algorithms Explain in detail uncertainty model validation concepts and techniques Devote a chapter to a review of the requisite mathematics Provide a concise yet self-contained appendix on several key relevant notions
