For overcoming the disadvantages of easily falling into local extremum and easily losing species diversity in traditional particle swarm optimization (PSO) algorithm, a cross improved PSO (IPSO) algorithm is proposed. In addition, in order to enhance the exploitation capacity of IPSO algorithm, it also makes use of chaotic sequence features which is called chaotic IPSO (CIPSO) algorithm. In present paper, mathematical structure model of hydro turbine governor is established, and the integral of absolute value of error as the minimum objective function is adopted to select particles. In order to obtain satisfactory transient dynamic characteristics in process of tuning of PID parameters, the square of output signal after PID tuning and the rise time are proposed to integrate into the augmented objective function, and in order to minimize overshoot to the greatest extent, the penalty mechanism is concerned. These algorithms are performed for optimized designs of governor PID parameters on hydro turbine. Several specific working conditions are modeled and CIPSO algorithm results are compared with those in PSO and IPSO algorithms. It comes out that the CIPSO algorithm has made some improvements whether in convergent speed or convergent accuracy in comparing with other two algorithms. © Sila Science. All rights reserved.

To explore crowd behaviors in coalmine emergency situations, a crowd evacuation simulation model was presented, which aims at the high-level decision-making skills and wayfinding algorithm to explore the leadership in underground emergency evacuation. In proposed evacuation model, leaders' and followers' behaviors were constructed according to their different roles and internal mental states. Leaders can explore coalmine environment for new paths using the proposed wayfinding algorithm to help others. The simulating results of underground fire evacuation case show the proposed approach is effective to create believable crowd behaviors in virtual coalmine. © 2013 Springer Science+Business Media.

International Journal of Digital Content Technology and its Applications 2012年第7期6卷 312-320页

作者： Cai, Linqin Zhang, Zhenhua Pan, Yuyou Xiong X., Juan Key Laboratory of Network control and Intelligent Instrument Chongqing University of Posts and Telecommunications Ministry of Education Chongqing 400065 China Research Center on Complex System Analysis and Control Chongqing University of Posts and Telecommunications Chongqing 400065 China

Emotion modeling is a vital part of human behavior simulation in stressful situation. Based on OCC appraisal theories, a fuzzy emotion model was proposed to simulate mine worker's emotional behavior response to underground hazardous events. Using fuzzy inference process, the proposed emotion model evaluates perceived event's impact on goal attainment and goal importance to generate emotion states for virtual miners. Moreover, mine worker's personality straits were taken into account in the intensity threshold of emotions, emotion's decay, and motivation update process according to OCEAN personality scales. And then, virtual miner's behaviors were implemented based on current motivation needs and emotion states. Finally, a hazards spotting case was reconstructed to validate the proposed model. Simulated results show virtual miner's fuzzy emotion model can assist in constructing more believable virtual coalmine environment, which helps train miner's decision-making ability when faced with occasional or emergency situations in underground coalmine.

Multi-agent based simulation for underground safety accidents

Journal of Convergence Information Technology 2011年第11期6卷 309-316页

作者： Cai, Linqin Pan, Yuyou Cen, Ming Yu, Jimin Key Laboratory of Network control and Intelligent Instrument Chongqing University of Posts and Telecommunications Ministry of Education Chongqing 400065 China Research Center on Complex System Analysis and Control Chongqing University of Posts and Telecommunications Chongqing 400065 China

Traditional experiments with human subjects for underground safety accidents are almost impossible because of safety and ethical issues. Based on Multi-agent technology, virtual mine architecture was presented to simulate underground safety accidents. In proposed multi-agent framework, multiple agents cooperate with each other through synchronization and message passing mechanisms to reveal the complex interactive characteristics of human-machine-environment related factors resulting in underground safety accidents. Furthermore, the design and implementation of virtual miner agent model was emphasized. Combined with internal attributes, virtual miner's behavior is constructed by a set of parameterized basic actions and controlled by personalized action selection mechanism. The simulating results on typical accidents of propdrawing operation in stope face show the proposed approaches are effective to reconstruct accident process in virtual mine for assisting underground safety accident analysis and prevention.

This paper evaluates the benefits to the lunar architecture and outpost of having a surplus of water, or a surplus of energy in the form of hydrogen and oxygen, as it has been predicted by Constellation Program's Lunar Surface system analyses. Assumptions and a scenario are presented leading to the water surplus and the revolutionary surface element options for improving the lunar exploration architecture and mission objectives. For example, some of the elements that can benefit from a water surplus are: the power system energy storage can minimize the use of battery systems by replacing batteries with higher energy density fuel cell systems;battery packs on logistics pallets can also be minimized;mobility asset power system mass can be reduced enabling more consumables and extended roving duration and distance;small robotic vehicles (hoppers) can be used to increase the science exploration range by sending round-trip robotic missions to anywhere on the Moon using in-situ produced propellants.

We address robust stabilization problem for networked control systems with nonlinear uncertainties and packet losses by modelling such systems as a class of uncertain switched systems. Based on theories on switched Lyapunov functions, we derive the robustly stabilizing conditions for state feedback stabilization and design packet-loss dependent controllers by solving some matrix inequalities. A numerical example and some simulations are worked out to demonstrate the effectiveness of the proposed design method.

The stabilization problem of networked control systems with bounded packet loss is addressed. We model such networked control systems as a class of switched systems, and present sufficient conditions for the stabilization by using a packet-loss dependent Lyapunov function. Moreover, different from existing results, we propose the design for packet-loss dependent stabilizing controllers for two types of packet-loss processes: one is a arbitrary packet-loss process, and the other is a Markovian packet-loss process. Several numerical examples and simulations are worked out to demonstrate the effectiveness of the proposed design technique.

Aboard current ships, such as the DDG 51, engineering control and damage control activities are manpower intensive. It is anticipated that, for future combatants, the workload demand arising from operation of systems under conditions of normal steaming and during casualty response will need to be markedly reduced via automated monitoring, autonomous control, and other technology initiatives. Current DDG 51 class ships can be considered as a manpower baseline and under Condition III typical engineering control involves seven to eight watchstanders at manned stations in the Central control Station, the engine rooms and other machinery spaces. In contrast to this manning level, initiatives such as DD 21 and the integrated engineering plant (IEP) envision a partnership between the operator and the automation system, with more and more of the operator's functions being shifted to the automation system as manning levels decrease. This paper describes some human systems integration studies of workload demand reduction and, consequently, manning reduction that can be achieved due to application of several advanced technology concepts. Advanced system concept studies in relation to workload demand are described and reviewed including. Piecemeal applications of diverse automation and remote control technology concepts to selected high driver tasks in current DDG 51 activities. Development of the reduced ship's crew by virtual presence system that will provide automated monitoring and display to operators of machinery health, compartment conditions, and personnel health. The IEP envisions the machinery control system as a provider of resources that are used by various consumers around the ship. Resource needs and consumer priorities are at all times dependent upon the ship's current mission and the availability of equipment pawnbrokers.
