Dynamic (average) consensus-based secondary control (SC) is a common and effective method to achieve distributed voltage recovery and load-sharing for multi-bus microgrids (MGs). However, dynamic consensus requires high communication and update rates, posing a high burden for communication networks, networked sensors, and controllers. Existing selftriggered mechanisms for conventional static average consensus are not suitable for dynamic consensus with exogenous inputs. Therefore, a novel self-triggered dynamic consensus-based SC is proposed in this paper for DC MG with networked sensors to reduce communication and computation burden. Stability of the self-triggered SC is demonstrated via Lyapunov analysis. Switchlevel simulations show that the proposed self-triggered strategy can significantly reduce communication and computation rates of SCs compared to the non-triggered and existing self-triggered strategies, and the proposed SC also demonstrates a faster convergence speed compared with the existing self-triggered SC. © 2024 IEEE.

In this work a parallel solution method for model predictive control is presented based on the alternating direction multiplier method. Our approach solves the overall problem by decomposing it along the time-axis into smaller subproblem. The resulting subproblems can be solved efficiently in parallel and are coupled by the multiplier update. We specifically considers box constraints, since this allows to use tailored methods to solve the subproblems. We outline the applicability of the approach and the performance using a multi-core systems. © 2012 IFAC.

Integration of Residual Evaluation and Threshold Computation into Switched Fault Detection System

引用

IFAC Proceedings Volumes 2012年第20期45卷 1238-1243页

This paper addresses problems related to the designing a fault detection (FD) for switched systems based on fault detection filter (FDF). The main contribution in this paper is to develop a residual evaluation and threshold computation scheme in an integration approach, to achieve an optimal FD for the switched systems. The basic idea behind this scheme is to utilize the available information provided by each local sub-model in the residual generation and evaluation, by constructing weighting factors, that reflect the effect of each local sub-model. In comparison with the standard FD methods, the proposed scheme will lead to a significant improvement in fault detectability for switched systems. The problem is formulated in the well-established LMI optimization techniques with Multiple Laypunov Functions (MLF).

Data-Driven Process Monitoring and Fault Tolerant control in Wind Energy Conversion System with Hydraulic Pitch System

Journal of Shanghai Jiaotong university(Science) 2015年第4期20卷 489-494页

作者：王凯罗浩 KRUEGER M DING S X 杨旭 JEDSADA S Institute for Automatic Control and Complex Systems University of Duisburg-Essen Baotou Vocational & Technical Collage School of Automation and Electrical Engineering University of Science and Technology Beijing Department of Electrical Engineering Faculty of Engineering Burapha University

Wind energy is one of the widely applied renewable energies in the world. Wind turbine as the main wind energy converter at present has very complex technical system containing a huge number of components,actuators and sensors. However, despite of the hardware redundancy, sensor faults have often affected the wind turbine normal operation and thus caused energy generation loss. In this paper, aiming at the wind turbine hydraulic pitch system, data-driven design of process monitoring(PM) and diagnosis has been realized in the wind turbine benchmark. Fault tolerant control(FTC) strategies focused on sensor faults have also been presented here, where with the implementation of soft sensor the sensor fault can be handled and the performance of the system is improved. The performance of this method is demonstrated with the wind turbine benchmark provided by Math Works.

In this paper, with the help of the Youla parameterization, the realizations of feedback control systems are discussed which results in a preferable and more convenient way to realize plug-and-play (PnP) control without modifying pre-designed control systems. Furthermore, based on the equivalence of different realizations of the Youla parameterization, a link between the standard feedback and the observer-based state feedback control system is given so that the well developed observer-based control techniques, like LQG/H2 control etc., can be achieved in the standard feedback control system via PnP control design. The effectiveness of the proposed PnP design schemes is verified using a direct current (DC) motor benchmark system. © 2017

Unit-level modelling for KPI of batch hot strip mill process using dynamic partial least squares

This paper proposes two different approaches to the problem of modelling the key performance indicators (KPIs) in a hot strip mill process (HSMP). The first approach takes into consideration the inherent dynamics of the process and develops a nonlinear iterative dynamic partial least squares (PLS) model. The second approach takes into consideration the multibatch property of HSMP to develop an appropriate multibatch modelling framework. Both approaches can be integrated into the dynamic model framework. The proposed framework is examined using industrial data obtained from a steel plant, where it provides a decent model for this process. However, there exists the potential for improvements including dealing with interbatch variability. © 2015, IF AC (International Federation of automatic control) Hosting by Elsevier Ltd.

This paper presents the research on the closed-loop data-driven design of the process monitoring system. The core of the study is the closed-loop identification of the data-driven stable kernel representation (SKR) of the system. The proposed method takes into account the effects of feedback controller and the noise information in the closed-loop is directly extracted from a single LQ decomposition. The main results and the proposed methods are verified and demonstrated through randomly generated numerical examples. © 2018

In this paper, a generalized likelihood ratio based detection algorithm with a statistical method for threshold setting is proposed to detect cyber-attacks on a unified remote control architecture. Based on an encoder and a decoder embedded on plant side and remote controller side, respectively, not only additive interrupted signal (only effecting output or input signal), but also multiplicative attack signal could be detected easily. Finally, three numerical examples are provided to validate our proposed scheme. © 2022 IEEE.

In this paper fault detection is addressed for networked control systems subject to random packet dropout in both sensor-to-controller link and controller-to-actuator link. First a new model of NCS is proposed, which directly eliminates influence of packet dropout in the sensor-to-controller link. Then adaptive threshold is given to ensure robustness to packet dropout in the controller-to-actuator link. False alarm rate analysis is also given, which is not addressed in most of the literature on fault detection of networked control systems. The fault detection scheme can ensure both robustness to packet dropout as well as disturbance and sensitivity to fault, which is superior to the existing approaches. Moreover, the residual generation can be achieved by using linear matrix inequality based convex optimization technique. Comparison with existing approaches illustrates advantages of our method. © 2009 IFAC.
