摘要
针对空间结构振动主动控制中的作动器位置优化问题,提出了一种改进的粒子群(PSO)优化方法,以系统总能量为性能指标进行优化;应用改进PSO方法对算例结构进行了计算,并与其他算法的优化结果进行了对比;结果表明:几种优化方法计算结果相符;且PSO优化算法能更有效快速地解决复杂优化问题,从而有效地进行结构的振动控制.
An improved particle swarm optimization (PSO) method is proposed for the position optimization of actuators in vibration control problems. The system energy is adopted as the optimal index in the method. A numerical example is calculated by the improved method and other optimal techniques. The results optimized by various methods are in good agreement, and the improved PSO method is more efficient for solving multiposition optimization problems of actuators in vibration control problems.
