International Conference on Information Science, Electronics and Electrical engineering (ISEEE)

作者： Xiang Wu Kanjian Zhang Changyin Sun Bangjun Lei Key Laboratory of Measurement and Control of Complex Systems of Engineering Southeast University Nanjing P.R.China

An optimal control problem of switched affine systems with continuous-time inequality constraints is considered in this paper. By introducing auxiliary piecewise constant function, Fischer-Burmeister function, control parametrization enhancing transform (CPET) and smoothing technique, the optimal control problem is transformed into a parameter optimization problem with a single linear equality constraint and simple bounds on the variables. Then, the original problem can be solved using any gradient-based method. Finally, a flying capacitor converter is solved to illustrate the efficiency of our method.

In steel industry, production planning of continuous casting and hot rolling are connected closely with each other. In addition, they are constrained by many key factors such as due date, process routes, and production capacity. Therefore, it is necessary to solve the production planning problems for continuous casting and hot rolling in an integrated way. In this research, we model the integrated production planning problem for continuous casting and hot rolling by mixed integer programming with the objective of minimizing the setup time and maximizing the utilization of devices, based on which a heuristic algorithm is developed to solve the problem. Numerical experiments are conducted to evaluate the proposed algorithm based on the data acquired from a steel plant in Jiangsu Province, China, and the results show that the proposed algorithm works quite well in integrated production planning of continuous casting and hot rolling.

Human flesh search(HFS), a Web-enabled crowdsourcing phenomenon, originated in China a decade ago. In this article, we present the first comprehensive empirical analysis of HFS, focusing on the scope of HFS activities, the patterns of HFS crowd collaboration process, and the characteristics of HFS participant networks. A survey of HFS participants was conducted to provide an in-depth understanding of the HFS community and various factors that motivate these participants to contribute. This article also advocates a new stream of Web science and social computing research that will be important in predicting the future growth and use of the World Wide Web.

This paper investigates the problem of sensitivity analysis for switched autonomous systems involving uncertain parameters. The aim is to find switching instants which minimizes the cost function, and meanwhile makes it robust to the variation of the original objective with respect to unknown parameters. We focus on the fixed switching mode sequences and convert the sensitivity problem into a conventional optimal switched control problem, which can be solved directly using the gradient descent algorithm. The efficacy of the proposed method is illustrated via numerical example.

2014 International Conference on Electrical,control and Automation(ICECA 2014)

作者： Liuhao Ge Zhengda Meng School of Automation Southeast University Key Laboratory of Measurement and Control of Complex Systems of Engineering Ministry of EducationSoutheast University

Current paint deposition modeling approaches did not consider the influence of variable spraying parameters. As spray painting robot has been widely used in paint application, there is a great need to be able to generate paint deposition model efficiently for robot path planning and simulation. In this paper, a layered framework for paint deposition modeling system is proposed, which uses the Back-Propagation（BP） neural network to model the relationship between spraying parameters（flow rate and atomizing pressure） and the paint deposition model. By using this modeling system, it isn’t necessary for users to conduct extra experiments when flow rate and atomizing pressure change. According to results of experiment and simulation, this method can predict paint deposition rate effectively.

Robust control reconfiguration of resource allocation systems with Petri nets and integer programming

Supervisory control reconfiguration can handle the uncertainties including resource failures and task changes in discrete event systems. It was not addressed to exploit the robustness of closed-loop systems to accommodate some uncertainties in the prior studies. Such exploitation can cost-efficiently achieve reconfigurability and flexibility for real systems. This paper presents a robust reconfiguration method based on Petri nets (PNs) and integer programming for supervisory control of resource allocation systems (RASs) subject to varying resource allocation relationships. An allocation relationship is seen as a control specification while the execution processes requiring resources as an uncontrolled plant. First, a robust reconfiguration mechanism is proposed. It includes updating the P-invariant-based supervisor and evolving the state of the closed-loop system. The latter adapts to the control specification changes by the self-regulation of the closed-loop system's state. Next, two novel integer programming models for control reconfiguration are proposed, called a reconfiguration model with acceptability and reconfiguration one with specification correction. Since both models integrate the firability condition of transitions, no additional efforts are required for the state reachability analysis. Finally, a hospital emergency service system is used as an example to illustrate them. © 2014 Elsevier Ltd. All rights reserved.

The paper presents a new approach on haptic interface control for NAO robotic hand. The haptic teleoperation of NAO robot hand raises some issues, mapping the haptic device dynamic being the most important. The mapping was achieved through Neural Network by determining a dynamic gain of robot haptic feedback. The results lead to the achievement of the haptic intelligent interfaces for the NAO robot hand control which can be integrated into an innovative haptic robot control system.

Adaptive fault-tolerant controller design for airbreathing hypersonic vehicle with input saturation

引用

Journal of systems engineering and Electronics 2013年第3期24卷 488-499页

作者： Haibin Sun Shihua Li Changyin Sun Key Laboratory of Measurement and Control of Complex Systems of Engineering(Ministry of Education) School of AutomationSoutheast University

The problem of fault-tolerant control is discussed for the longitudinal model of an airbreathing hypersonic vehicle （AHV） with actuator faults and external disturbances. Firstly, a fault-tolerant control strategy is presented for the longitudinal model of an AHV, which guarantees that velocity and altitude track their reference trajectories at an exponential convergence rate. However, this method needs to know the minimum value of the actuator efficiency factor and the upper bound of the external disturbances, which makes it not easy to implement. Then an improved adaptive fault-tolerant control scheme is proposed, where two adaptive laws are employed to estimate the upper bound of the external disturbances and the minimum value of the actuator efficiency factor, respectively. Secondly, the problem of designing a control scheme with control constraints is further considered, and a new adaptive fault-tolerant control strategy with input saturation is designed to guarantee that velocity and altitude track their reference trajectories. Finally, simulation results are given to show the effectiveness of the proposed methods.
