Title:FAS Models for Strict-Feedback Systems with Nonuniform Dimensions
Abstract: This talk extends the existing works on fully-actuated system (FAS) models for strict-feedback systems (SFSs). We consider control problems for SFSs with nonuniform dimensions. In particular, the subsystems in the considered SFSs are assumed to have increasing dimensions, which is different from and also more complex than the commonly-considered SFSs where the subsystems have the same dimension. The systems are transformed into FAS models, based on which the stabilizing controllers can be directly given. Besides first-order SFSs, second-order and high-order SFSs are also considered.

Title: Theoretical exploration and practice of industrial process fault diagnosis based on zero sample learning
Abstract: Fault diagnosis system is an important guarantee for the safe and reliable operation of industrial processes. Data-driven fault diagnosis modeling often depends on the collected sufficient historical fault data. However, in actual industrial processes, it is common that process failures have no historical samples and no labels. In this regard, we need to deal with a very challenging fault diagnosis task, that is, to consider diagnosing when there are no historical fault samples available for model training. We introduced the concept of zero-shot learning into the industrial field for the first time, and innovatively established a zero-shot-learning fault diagnosis method. By skillfully introducing a priori modeling knowledge with fault description as the carrier and adopting the attribute migration method, we overcame the concerned bottleneck problem that traditional fault diagnosis research cannot meet the sample size constraint. The fault diagnosis effects in the case of zero samples are verified in the real megawatt thermal power process, and the results show that it is feasible to diagnose unseen target fault without samples. On this basis, the existing challenges, difficulties and future research directions are revealed.

Title: Adaptive Parameter Estimation and Control via Estimation Error: Theory and Application
Abstract: Adaptive parameter estimation and adaptive control have been well developed to achieve modeling and control for uncertain systems. However, the well-known parameter estimation and adaptive control methods have been mainly designed based on the gradient algorithms (with appropriate modifications) by using the prediction error or control error. Hence, the parameter estimation convergence and the online verification of the required persistent excitation (PE) condition are generally difficult with this framework. In this talk, we will introduce a novel robust, fast adaptive parameter estimation framework, where the estimation error between the unknown parameters and their estimates are explicitly obtained and then use to drive online adaptation algorithms. This new adaptation even allows to achieve finite-time parameter estimation, and can be easily incorporated into adaptive control designs to achieve tracking control and parameter estimation simultaneously. We will also introduce an intuitive and numerically feasible approach to online verify the PE condition. Finally, several practical application of this new adaptation to in-car parameters estimation, ITER cryogenics system identification, and adaptive control for robotics, wave energy converters (WECs) and other realistic systems will be presented.
