| 1 | 基于遗传算法和粒子群优化的模糊PID控制器在双星感应电机直接转矩控制中的应用(英文)显示文摘本文对双星感应电动机直接转矩控制的三种混合方法进行了分析、控制和比较,目的是将PID-PSO、模糊 PSO 和 GA-PSO 三种不同的启发式优化技术相结合,以改善 DSIM 速度控制回路的性能。将遗传算法和粒子群优化算法应用于 MATLAB,得到模糊粒子群算法是最合适的方案。模糊粒子群算法的主要性能是减小了大扭矩波动,加快了上升时间,避免了影响驱动性能的干扰。 | BOUKHALFA Ghoulemallah BELKACEM Sebti CHIKHI Abdesselem BENAGGOUNE Said | 2019 | Journal of Central South University2019，26，7： | 9 |
| 2 | A two variable refined plate theory for the bending analysis of functionally graded plates显示文摘Bending analysis of functionally graded plates using the two variable refined plate theory is presented in this paper.The number of unknown functions involved is reduced to merely four,as against five in other shear deformation theories. The variationally consistent theory presented here has, in many respects,strong similarity to the classical plate theory. It does not require shear correction factors,and gives rise to such transverse shear stress variation that the transverse shear stresses vary parabolically across the thickness and satisfy shear stress free surface conditions.Material properties of the plate are assumed to be graded in the thickness direction with their distributions following a simple power-law in terms of the volume fractions of the constituents.Governing equations are derived from the principle of virtual displacements, and a closed-form solution is found for a simply supported rectangular plate subjected to sinusoidal loading by using the Navier method.Numerical results obtained by the present theory are compared with available solutions,from which it can be concluded that the proposed theory is accurate and simple in analyzing the static bending behavior of functionally graded plates. | Ismail Mechab Hassen Ait Atmane Abdlouahed Tounsi Hichem Abdesselem Belhadj EI Abbas Adda Bedia | 2010 | Acta Mechanica Sinica2010，26，6： | 2 |

| 9 | A fuzzy trust-based routing model for mitigating the misbehaving nodes in mobile ad hoc networks显示文摘Purpose–Security is one of the major challenges in the design and implementation of protocols for mobile ad hoc networks(MANETs).In such systems,the cooperation between nodes is one of the important principles being followed in the current research works to formulate various security protocols.Many existing works assume that mobile nodes will follow prescribed protocols without deviation.However,this is not always the case,because these networks are subjected to a variety of malicious attacks.Since there are various models of attack,trust routing scheme can guarantee security and trust of the network.The purpose of this paper is to propose a novel trusted routing model for mitigating attacks in MANETs.Design/methodology/approach–The proposed model incorporates the concept of trust into the MANETs and applies grey relational analysis theory combined with fuzzy sets to calculate a node’s trust level based on observations from neighbour nodes’trust level,these trust levels are then used in the routing decision-making process.Findings–In order to prove the applicability of the proposed solution,extensive experiments were conducted to evaluate the efficiency of the proposed model,aiming at improving the network interaction quality,malicious node mitigation and enhancements of the system’s security.Originality/value–The proposed solution in this paper is a new approach combining the fundamental basics of fuzzy sets with the grey theory,where establishment of trust relationships among participating nodes is critical in order to enable collaborative optimisation of system metrics.Experimental results indicate that the proposed method is useful for reducing the effects of malicious nodes and for the enhancements of system’s security. | Abdesselem Beghriche Azeddine Bilami | 2018 | International Journal of Intelligent Computing and Cybernetics2018，11，2： | 0 |
| 10 | 遗传算法优化的模糊二阶滑模控制在双星感应电机的直接转矩控制中的应用显示文摘采用传统PI控制器对双星感应电机(DTC-DSIM)进行直接转矩控制性能并不理想,可能造成转矩和磁通量波动大,对参数变化敏感等。在经典驱动中能够克服上述缺点的控制策略之一就是将超螺旋算法(STA)与模糊逻辑控制相结合的模糊二阶滑模控制方法(FSOSMC)。未来实现最优控制效果,采用遗传算法(GA)对FSOSMC参数进行优化。将本文中的G-FSOSMC算法与G-SOSMC、G-PI和BBOFSOSMC进行性能比较,结果表明,G-FSOSMC能有效地减小转矩和磁通量波动,并抑制电机颤振;且参数的不确定性也不影响系统性能。 | Ghoulemallah BOUKHALFA Sebti BELKACEM Abdesselem CHIKHI Moufid BOUHENTALA | 2022 | Journal of Central South University2022，29，12： | 0 |
