Abstract: 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 multi-position optimization problems of actuators in vibration control problems.

Key words: particle swarm optimization (PSO) method
