講座人介紹：

Tarek Ra?ssi為法國國立工藝學(xué)院教授，主要研究領(lǐng)域包括動態(tài)系統(tǒng)的狀態(tài)與參數(shù)估計、故障檢測與分離、容錯控制、故障預(yù)知等。Tarek Ra?ssi教授作為故障診斷和容錯控制方面的知名學(xué)者目前為IEEE資深會員，多次擔(dān)任關(guān)于故障診斷和容錯控制方面的國際會議的程序委員會專家和分會主席。目前針對不確定性系統(tǒng)、非線性系統(tǒng)以及切換系統(tǒng)等不同類型復(fù)雜系統(tǒng)，Tarek Ra?ssi教授采用集合元素估計和區(qū)間觀測器技術(shù)，在系統(tǒng)狀態(tài)和參數(shù)估計，以及故障診斷和容錯控制等方面積累了豐富成果。Tarek Ra?ssi教授目前發(fā)表SCI期刊論文70多篇，自2019年至今論文引用超3700多次，此外參與2部控制理論相關(guān)專著撰寫。

講座內(nèi)容：

The goal of set-membership estimation is to compute sets of admissible values of the state vector at each instant of time for systems subject to bounded uncertainties such as measurement noise, disturbances and uncertain parameters. The size of the estimated sets, which should be minimized, has to be proportional to the model uncertainties. A set estimation can be seen as a conventional point estimation (the center of the set) with an estimation error given by the radius of the geometrical set. The reliable uncertainties propagation performed in this context can be useful in several fields such as robust control, diagnosis and fault-tolerant control. During this lecture some recent results developed for linear and nonlinear systems (both continuous and discrete-time cases) based on ellipsoids and intervals will be presented. Based on numerical simulations, it will be shown that these innovative approaches can overcome the limitations of standard interval observer techniques.
