报告摘要(Abstract):

A key benefit of utilization of a two-dimensional/repetitive framework will be emphasized. To design the desired feedback and learning controllers the frequency-domain methods are applied together with robust control theory to formulate the general design framework for the ILC scheme. The resulting problem of determining required feedback and learning controllers is reduced to that of checking the existence of a solution constrained by a set of linear matrix inequalities. That can be efficiently solved in terms of semi-definite programming algorithms, creating a very attractive approach from the point of view of computational burden. Also, a link between these results and practical requirements for developed control schemes, which are usually described by multiple frequency domain inequalities in (semi)finite frequency ranges, will be explored. Specifically, with aid of the generalized version of Kalman-Yakubovich-Popov (KYP) lemma, ILC design in finite frequency ranges is performed. This approach allows the designer to specify a frequency range where tracking of the reference signal is required, where, for example, this range could be determined by inspection of frequency spectrums of the signal to be tracked. Therefore, a better tracking performance is expected. Some examples will be also given during this presentation to illustrate the developed results.
