Research On Simulation Platform For Equipment System Analysis, Yuping Li, Shaojie Mao, Zhenqi Ju, Zhou Fang, Guoqiang Yan
Journal of System Simulation
Abstract: With the development of equipment construction from platform-centric to network-centric, simulation analysis of equipment system is an important means and tool to support the transformation and development of equipment construction under the condition of multi-task joint operation. Starting from the requirement of system simulation analysis, a cloud-based equipment system simulation architecture is proposed to realize flexible and configurable simulation environment according to task requirements; and a high-performance simulation framework is conducted, which provides strong support for different application modes, such as parallel hyper-real-time and distributed simulation deduction. The unified description, organization and management method of model and data resources …

Fractional-Order Memristor Model With Nonlinear Drift Function, Zhaohui Gan, Shiying Zhang, Yuxin Wu
Journal of System Simulation
Abstract: A memristor is a nonlinear resistor with memory. It is regarded as the fourth basic circuit elements. The fractional order model of memristor is an extension of integer order model for memristor. Some researchers have confirmed the existence of fractional order model for memristor, and the response characteristic of the fractional order model excited by different types of signals is analyzed. Based on the analysis of some existing integer order and fractional order models for memristor, a novel fractional order memristor model with nonlinear drift function is proposed, and the response characteristics of fractional order model for memristor with …

Method Research On Collaborative Simulation Of Multi-Resolution Models, Gaofeng Zhang, Yujie Ji
Journal of System Simulation
Abstract: The collaborative simulation of multi-resolution models is an effective method to meet the requirement of “wide-area confrontation and local high imitation” in combat simulation. The generalized supporting platform for multi-resolution models collaborative simulation is constructed, and the collaborative simulation mechanism with mirror entity and control right dynamic migration as core technology is proposed, which can effectively solve the problem of interconnection and homomorphic mapping between multi-resolution models, as well as collaborative operation consistency issues. Under the support of this technique, the joint operation among different resolution models in a tactical deduction simulation system is stable, efficient and consistent. This …

Mining And Validation Of Attacking Behavior In The Robocup 2d Simulation, Chen Bing, Zhang Heng, Zekai Cheng, Dong Peng, Lin Chao
Journal of System Simulation
Abstract: Robocup is an international academic competition which focuses on artificial intelligence and robotics. The 2D simulation is one of the earliest and most influential projects in Robocup. Attacking is the core behaviour of the simulated football game, as well as the attack recognition is considered as an important part in team-confrontations. This paper selects some active and contribution index of attacking, extracts lots of attacking behaviour data of the key agents, proposes two kinds of attacking patterns of 2D simulation, as ‘separate attack’ and ‘cooperative attack’, according to the human-player actions. The following simulation tests give the accuracy of …

Modeling And Simulation Of Difg Unit With Stator Inter-Turn Fault, Boqiang Xu, Liling Sun, Wenjuan Du
Journal of System Simulation
Abstract: The mathematical model of doubly fed induction generator (DFIG) with stator inter-turn fault, which presents itself as standard form state space equation, is deduced and established, for the first time. The corresponding simulation model, i.e. Matlab S-function block is developed and embedded in a Matlab built-in routine simulating DFIG unit comprising wind turbine, converter, related mechanical/electrical control and DFIG. The simulation model of DFIG unit with stator inter-turn fault is established, which is a beneficial extension of Matlab simulation. The stability of DFIG unit under the healthy and faulty conditions is analyzed by using simulation. The results show …
