1.報(bào)告會(huì)簡(jiǎn)介
報(bào)告人：郭寶珠研究員
時(shí)間：2020年12月01日(星期二) 19：00
地點(diǎn)：騰訊會(huì)議（會(huì)議號(hào)：316461735）
報(bào)告題目：Active Disturbance Rejection Control: From ODEs to PDEs
內(nèi)容簡(jiǎn)介：Active disturbance rejection (ADRC) is a new emerging control technology which is used to deal with large internal uncertainties and external disturbances for control systems. Its effectiveness has been witnessed many numerous engineering applications. Basically, ADRC is composed of three arts. The first part is the tracking differentiator (TD) which is used to estimate the derivatives of the reference signals. The second part is the extended state observer (ESO) which is used to estimate both state and the total disturbance that includes internal uncertainty and external disturbance. The third part is about ESO based feedback control, something like the separation principle in control theory. In this talk, I will introduce some established theoretical results of ADRC for ODEs and its extension to some PDEs.
