講座人介紹:
W.M. Wonham教授是加拿大皇家科學(xué)院院士,美國(guó)工程院外籍院士,IEEE終身會(huì)士。他于1956年獲得麥吉爾大學(xué)的工程物理學(xué)學(xué)士學(xué)位,并于1961年獲得了劍橋大學(xué)(英國(guó))的控制工程博士學(xué)位。從1961年到1969年,他與美國(guó)幾個(gè)控制研究小組有聯(lián)系,這些研究小組包括高級(jí)研究所(RIAS),布朗大學(xué)的應(yīng)用數(shù)學(xué)系和NASA的電子研究中心。自1970年以來(lái),他一直是多倫多大學(xué)電氣與計(jì)算機(jī)工程系系統(tǒng)控制的教員。他于1996年成為“大學(xué)教授(University Professor)”。
Wonham的研究興趣包括隨機(jī)控制和過(guò)濾,幾何多變量控制以及離散事件系統(tǒng)。他是《Linear Multivariable Control: A Geometric Approach》(Springer-Verlag:3rd edn 1985)的作者,還是《Nonblocking Supervisory Control of State Tree Structures》(Springer-Verlag:2005)的合著者(與C. Ma合作)。 與“Kai Cai”合著(“Supervisor Localization: A Top-Down Approach to Distributed Control of Discrete-Event Systems”(Springer-Verlag:2015年),以及“Supervisory Control of Discrete-Event Systems”,在1997-2015年間每年更新。他在期刊上發(fā)表了100多篇研究文章,并指導(dǎo)了60多名碩士和博士學(xué)位候選人。
講座內(nèi)容:
The Internal Model Principle (IMP) of control theory states (informally) that "a good controller incorporates a model of the dynamics that generate the signals which the control system is intended to track." Briefly, the controller contains a model of its "exosystem", or "outside world." While formal statements have appeared in the control literature starting in the 1970s, these have been developed only within rather specialized frameworks such as linear multivariable systems or certain nonlinear systems defined on smooth manifolds.
Our aim in this lecture is to sketch a version of the IMP in as elementary a setting as possible, namely just that of plain sets and functions. In particular we discuss the necessity of feedback, and how from feedback structure the controller's internal model structure can be naturally
derived. While many questions remain open, this setting has the appeal of being universal and readily specialized. We conclude with a brief summary of current research topics.
