This paper proposes an improved auction algorithm to optimize the efficiency of dynamic weapon target assignment (WTA) problem. Firstly, the dynamic battlefield environment of firepower-health model is analyzed and the constraints of weapon assignment problem are established. The firepower-health model is about the idea of adding constraints of weapon firepower and target health to promote the result of assignment more effectively. Secondly, in order to improve the computing speed of WTA algorithm, the penalty mechanism is introduced in the compensation auction algorithm. The main idea of improved algorithm is to reduce the extra consuming of the weapon during the assignment, from which penalty mechanism can optimize the assignment results and reduce the number of algorithm iterations by punishing the overkilled target under certain rules. Finally, the simulation results based on the dynamic firepower-health model show that the proposed algorithm can meet the requirements of firepower allocation, and can promote the effectiveness of assignment with high real-time response. © 2023 Technical Committee on control Theory, Chinese Association of automation.

In modern aircraft, the deployment and retraction of thrust reverser cowls are facilitated by multiple linear actuators operating in concert. This configuration, while effective, introduces synchronization challenges due to the simultaneous action of the actuators. To address this issue, flexible steel shafts are incorporated to interconnect the actuators, and a closed-loop control system is implemented to manage their operation. The inherent low stiffness non-linearity of the flexible shafts, combined with the system's multiple inertias, significantly increases the susceptibility of motor speed and load speed to resonance. This paper introduces a prototypical transmission system to elucidate these dynamics. It constructs a dual-inertia servo system model, investigates the principal factors contributing to system resonance, and extends this to a more comprehensive three-inertia model. Through rigorous simulation experiments, the paper validates the developed model, thereby laying a theoretical foundation for the design of more robust control strategies. © The Institution of engineering & Technology 2024.

Time-Critical Wireless Network (TCWN) is a promising communication technology that can satisfy the low latency, high reliability, and deterministic requirements of mission-critical applications. Multiple TCWNs required by various applications inevitably coexist with each other. Most existing works aim to achieve acceptable latency or consider the simplest topology (i.e., line topology). As latency requirements become more stringent, exploring the minimum data collection latency becomes an interesting problem. In this paper, the coexisting system consists of multiple tree-topology-based TCWNs. We first establish a conversion framework to convert an arbitrary tree topology into multiple analogous line topologies to reduce the analysis complexity. We then propose a Time-Critical wireless network Scheduling (TCS) algorithm to minimize the data collection latency of coexisting TCWNs. The TCS algorithm consists of two phases. In the internetwork scheduling phase, we strictly derive a general expression to characterize the practical network requirements. In the intranetwork scheduling phase, we design two levels of priority assignment algorithms to accurately characterize the critical states and resource requirements of different nodes. We conduct extensive simulations to verify the effectiveness of the TCS algorithm. The evaluation results show that the TCS algorithm can achieve minimum data collection latency in more than 99.956% cases, and the maximum difference compared to the optimal value is one time slot. © 2004-2012 IEEE.

In this paper, an incentive mechanism is developed to maximize the weighted social welfare for pseudo-gradient-based noncooperative dynamical systems. In the proposed approach, the system manager manipulates agents' decision making by collecting taxes and giving subsidies to the agents under a sustainable budget constraint using the partial knowledge related to the payoff structure from the agents except a secret agent. To avoid direct acquisition of the payoff information of all the agents, our idea is to shift the stationary points of those partial agents and hence indirectly move the Nash equilibrium of the entire system. Sufficient conditions are derived under which the Nash equilibrium is shifted towards the target state achieving Pareto efficiency under the incentive mechanism without knowing any payoff information of the secret agent. Some convergent conditions to ensure agents' state converge to the target state under a sustainable budget are provided for the given initial state. We present a numerical example to illustrate the efficacy of our results. © 2024 IEEE.

Fault Diagnosis Based on the Updating Strategy of Interval-Valued Belief Structures

引用

Chinese Journal of Electronics 2025年第4期23卷 753-760页

作者： Xiaobin Xu Ping Liu Yanbo Sun Chenglin Wen Institute of Systems Science and Control Engineering School of Automation Hangzhou Dianzi University Hangzhou China Department of Control Science and Engineering School of Astronautics Harbin Institute of Technology Harbin China

This paper presents the dynamic method for fault diagnosis based on the updating of Interval-valued belief structures (IBSs). The classical Jeffrey's updating rule and the linear updating rule are extended to the framework of IBSs. Both of them are recursively used to generate global diagnosis evidence with the form of Interval basic belief assignment (IBBA) by updating the previous evidence with the incoming evidence. The diagnosis decision can be made by global diagnosis evidence. In the process of evidence updating, the similarity factors of evidence are used to determine switching between the extended Jeffrey's and linear updating rules, and to calculate the linear combination weights. The diagnosis examples of machine rotor show that the proposed method can provide more reliable and accurate results than the diagnosis methods based on Dempster-Shafer evidence theory.

controllability of game-based multi-agent system

We introduce a strategy matrix, a novel concept for ensuring controllability in game-based control systems(GBCSs). This graph-based condition is presented as an alternative to utilizing complex mathematical calculations through algebraic conditions. Moreover, to address these issues, one must first study the expression of Nash equilibrium actions. This expression yields a general formula of the game controllability matrix, which is always affected by the specific matrix(strategy matrix) comprising Nash equilibrium actions, and the matrix can not only be obtained by matrix calculation but can also be directly written through the topology, indicating the topology's specific influence on the GBCS. Finally, we build a new game-based multi-agent system and determine the controllability relationship between the system and the general system.

Dual-super satellite is a new type of spacecraft structure that separates the satellite platform and payload, and blocks the transmission of micro-vibrations from the platform through mechanical isolation to provide an ultra-precise and ultra-stable payload environment. However, the cable used for energy supply and communication of the payload has an impact on the pointing performance of the payload. In order to solve the uncertainty of the payload dynamics model brought by the flexible cable and the low-frequency bounded interference problem, this paper proposes a sliding mode adaptive control method for the payload under the influence of cables. A feedforward compensation algorithm based on partial state observer is designed for bounded disturbance of satellite platform. The control method presented in this paper ensures the pointing performance of the payload during agile maneuvers, and demonstrates robustness against model uncertainty and low-frequency disturbances caused by cables through simulation studies. © The Author(s) Hangzhou 310023, under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Multiphase permanent magnet (PM) synchronous machine features the advantages of high reliability and high fault-tolerant capability, which has great potential in the fields like aviation servo and electric vehicles. In order to meet the design criteria of low moment of inertia and high post-fault torque performance, three different rotor structures are analyzed and compared for a low-inertia fault-tolerant permanent magnet synchronous machine(SLIFT-PMSM) by finite-element method. The influence of winding structure on torque performance is investigated, and the winding structure is optimized to improve the post-fault torque performance. The electromagnetic performance of the improved scheme is evaluated under both the normal and fault conditions. © 2024 IEEE.
