Title:ata-driven wide-range nonstationary process monitoring

Abstract: Modern industrial production often has wide-range nonstationary operating characteristics, such as batch manufacturing processes, wide-load power generation processes, etc. Due to its large-scale non-stationary operation characteristics, it raises new challenges to the safe and reliable operation of industrial processes and has become the focus of attention. Starting from the traditionl batch process, this report will present the concept of a generalized batch process, analyze the specific characteristics of wide-range nonstationary industrial processes, and summarize the basic process monitoring techniques and the relevant research work in this field. It further analyzes the existing specific problems, and extend the traditional batch process analysis methods to industrial processes with wide-range non-stationary operation characteristics. Finally, the application of the proposed method in different fields will be briefly introduced.

TitleDynamic reference programming-based model predictive

            pattern control by dynamic controlled PCA

Abstract: A dynamic controlled principal component analysis (DCPCA) algorithm is proposed to extract desirable latent variables and construct the pattern space of industrial process from a set of measured variables. The constructed pattern space contains the most variations of process variables caused by free motion, as well as the forced movement subjected to the causality originating from control inputs. Consequently, the pattern can characterize the process running state maximally and comprehensively with the minimum dimensions, and the pattern motion equation can be identified to describe the dynamic behavior of industrial plant. After that, a dynamic reference programming-based MPC is designed to drive pattern to track the optimal operation point with zero steady-state error if the target is reachable, otherwise the pattern is steered to a suboptimal but closest position to the target. This MPC strategy is characterized by parameterized reference inputs and enlarged terminal constraint set derived from null space analysis, which could guarantee the maximum reachable optimization area is lossless when solving the objective function.

Title:Data driven brain neurofiber tract identifcation

Abstract:Accurate brain neurofiber tract identification promises to have a high impact in fundamental neuroscience and its clinical applications. However, state-of-the-art fiber tracking algorithms are driven by local symmetrically orientation fields estimated from diffusion MRI, representing the local tangent direction to the white matter tract of interest. Conceptually, the principle of inferring connectivity with streamline prorogation from local symmetrically orientation fields can lead to problems as soon as pathways overlap, cross, branch, and have complex geometries. Usually, tractography-based connectome is dominated by lots of false-positive connections. This project will propose an asymmetric tensor stream-flow fiber tracking methods and its application in cranial nerve atlas reconstruction. Firstly, a stream-flow differential equation based on computational fluid mechanics will be presented for describing nerve fiber bundle. The asymmetric fiber geometries is expressed as the distribution of streamline cluster in tensor vector field which extends the streamline prorogation to more general stream-flow way. Then, an data driven automated neurofiber tract identification algorithm will be proposed for connectome-based cranial nerve tractographic atlas based on asymmetric global fiber tracking. Its potential clinical applications in neurosurgical planning and neurodegenerative diseases are presented.

Title: Prediction and Scheduling for Industrial Energy System

Abstract: Industrial energy resource saving is capable of not only improving the enterprise profits, but also carrying out the significant strategy meaning for our country. Given the fixed technical process and equipment, the optimization scheduling of the industrial energy system is the most important approach for such a goal. However, the most industrial energy systems exhibit a very complicated structure, which can hardly establish a mechanism based model to describe such a system, and the existing manual scheduling method makes the decision making process tardily. A class of data-driven predictive scheduling methodology is proposed. In detail, considering the consistent modeling, the quantitative uncertainty description, and the semantic characteristics of the energy data, the short-term prediction model, the prediction interval one and the long-term model are respectively reported, and a rolling optimization technique with the procedures of prediction-scheduling-validation is proposed. The mentioned approaches have been successfully applied to a number of industrial enterprises in our country.

Title:Distributed Gradient Tracking for Optimization and

             Learning over Networks

Abstract: Many problems of recent interest in control and machine learning can be posed in the framework of mathematical optimization. As data gets larger and more distributed, distributed algorithms over networks offer ample opportunities to improve the speed and accuracy of optimization. In this talk, we shall exploit the distributed gradient tracking technique (DGT) to solve large-scale optimization and learning problems, e.g., the fully Asynchronous DGT which is easy to implement in directed networks with distributed datasets and robust to bounded transmission delays, while maintaining a linear convergence rate if local functions are strongly-convex with Lipschitz-continuous gradients. Moreover, we adopt the DGT to design distributed algorithms with explicit convergence rates for the distributed resource allocation and distributed training over networks, respectively. Experiments are included to show their advantages against the-state-of-the-art algorithms.

Title:Iterative Learning Control with Incomplete Information

Abstract:Iterative learning control is an effective control strategy for repetitive systems by utilizing the input and output information of the previous iterations. It has been shown advantageous in dealing with high nonlinearity and complexity while achieving good tracking performance of high precision. In this talk, we will report recent advances in iterative learning control with incomplete information. Here, incomplete information is generally caused by various practical issues such as data dropout, quantization, varying trial lengths, and communication constraints. The control design and analysis under these issues will be elaborated.

TitleNon-Intrusive Modeling for We-Energy based on Mechanism-Data      

             Hybrid Drive

AbstractGenerally, an accurate model can describe the operating status of a system more effectively and provide a more reliable theoretical basis for the system optimization and control. To distinguish from the traditional invasive modeling, a non-invasive modeling method based on mechanism and data hybrid is proposed for we-energy, a typical energy system. By using this method, non-invasive modeling for the energy system including photovoltaic, wind power, energy storage devices and energy coupling devices can be carried out. Firstly, the meteorological data, energy output and price curve are utilized to analyze and extract the characteristic of we-energy, and then the characteristic database is established. Afterwards, by taking the port energy data of we-energy as the random noise input, the GAN generator is improved and more applicable to we-energy characteristic. The feedback evaluation of GAN discriminator is utilized to guide the generator model, and we-energy model is established by the output of the discriminator. This model can accurately demonstrate the static and dynamic characteristic of the terminal integrated energy unit, laying a foundation for the collaborative optimization of the integrated energy system.
