Hybrid variable neighbourhood search for multi-objective bus driver rostering

Journal of Computational and Theoretical Nanoscience 2016年第6期13卷 3989-3996页

Bus driver rostering is a world-wide problem, which is NP-hard. Two objectives exist in the problem: (1) minimizing the number of drivers;(2) minimizing excess workload of each driver and balancing excess workload among the drivers. To solve the problem, a Hybrid Variable Neighbourhood Search (HVNS) approach is developed, in which two compound neighbourhood structures are devised, each corresponds to an objective and the two neighbourhood structures are employed in turn. Simulated Annealing (SA) is integrated into the HVNS to serve as a solver for neighbourhood search. In the SA, the traditional acceptance criterion is enhanced by accepting 'deteriorated' solutions with control and probability without losing the randomness;moreover, two evaluation functions are built to handle user preferences. Experiments show that the proposed HVNS can produce good results. Copyright © 2016 American Scientific Publishers. All rights reserved.

Coordinated control of multi-agent systems has widespread application in engineering such as unmanned aerial vehicles and unmanned ground vehicles. Due to the fact that input saturation can lead a control system to deterioration and instability, a lot of efforts have been devoted to investigating this subject of great importance. The present article offers a survey of recent developments on coordinated control of multi-agents systems subject to input saturation. Some preliminaries about graph theory, stability theory and input saturation are first provided, followed by some important results in the area, which are categorized into semi-global and global coordinated controls. Future research topics are finally discussed.

This technical note deals with a modified algebraic Riccati equation (MARE) and its corresponding inequality and difference equation, which arise in modified optimal control and filtering problems and are introduced into the cooperative control problems recently. The stabilizing property of the solution to MARE is presented. Then, the uniqueness is proved for the almost stabilizing and positive semi-definite solution. Next, the parameter dependence of MARE is analyzed. An obtained parameter dependence result is finally applied to the study of semi-global synchronization of leader-following networks with discrete-time linear dynamics subject to actuator saturation. © 1963-2012 IEEE.

An adaptive differential evolution approach for the maximal synchronization problem of feeder buses to metro

引用

Journal of Computational and Theoretical Nanoscience 2016年第6期13卷 3548-3555页

作者： Shen, Yindong Wang, Siqi Key Laboratory of Image Processing and Intelligent Control Huazhong University of Science and Technology Ministry of Education Wuhan Hubei430074 China School of Automation Huazhong University of Science and Technology Wuhan430074 China

This paper presents an adaptive differential evolution approach (DEMS for short) for the maximal synchronization between two most popular transit modes (i.e., bus and metro). Given a metro station, suppose the timetable of the metro system is precompiled, the DEMS approach is to produce timetables for the bus lines passing through the transfer points around the metro station. The objective is to achieve a maximal synchronization amongst the buses and metro. This is helpful to increase the ridership of metro systems and enhance the service level of an entire public transport system. In this paper, three types of simultaneous arrival are first defined, before an integer programming model is built for the maximal synchronization problem. Then, the DEMS approach is devised to solve the problem. Experiments on benchmark instances and a case study on a realworld problem demonstrate that the proposed DEMS approach can produce good results and is promising with good behavior of convergence.

Robust reliable guaranteed cost control of positive interval systems with multiple time delays and actuator failure

引用

International Journal of Systems Science 2016年第4期47卷 946-955页

This paper addresses the robust reliable guaranteed cost control problem of positive interval systems with multiple time delays and actuator failure for a given quadratic cost function. Through constructing a Lyapunov-Krasovskii functional, a sufficient condition for the existence of robust reliable guaranteed cost controllers is established such that the closed-loop system is positive and asymptotically stable, and the cost function is guaranteed to be no more than a certain upper bound. Based on the linear matrix inequality method, a criterion for the design of robust reliable guaranteed cost controllers is derived which can tolerate all admissible uncertainties as well as actuator failure. Moreover, a convex optimisation problem with linear matrix inequality constraints is formulated to design the optimal robust reliable guaranteed cost controller which minimises the upper bound of the closed-loop system cost. A numerical example is given to show the effectiveness of the proposed methods. © 2014 Taylor & Francis.

Event-Triggering Load Frequency control for Multiarea Power Systems with Communication Delays

引用

IEEE Transactions on Industrial Electronics 2016年第2期63卷 1308-1317页

作者： Wen, Shiping Yu, Xinghuo Zeng, Zhigang Wang, Jinjian School of Automation Key Laboratory of Image Processing and Intelligent Control Ministry of Education of China Huazhong University of Science and Technology Wuhan430074 China Platform Technologies Research Institute RMIT University MelbourneVIC3001 Australia

This paper studies the load frequency control (LFC) for power systems with communication delays via an event-triggered control method to reduce the amount of communications required. The effect of the load disturbances on the augmented output is defined as a robust performance index of the augmented LFC scheme. By utilizing a time-delayed system design approach, a new model of the LFC scheme with delays is formulated, where the communication delays and event-triggered control are integrated for the LFC scheme. Based on the Lyapunov-Krasovskii functional method, the criteria for the event-triggered stability analysis and control synthesis of the LFC scheme are derived. Finally, the effectiveness of the proposed method is verified by simulation studies. © 1982-2012 IEEE.
