Based on the system reserve energy index as objective optimization function of the structure vibration system, sets up the multi-objective optimal disposition mathematical model which refer to the system control gain and the sensors and actuators placements, quantities, lengths of the active vibration control system, adopts the multi-island genetic algorithm (MIGA) as optimization strategy. Experiments with intelligent cantilever beam as an example, the vibration control effect is very distinct. Hence, approves the method correctness and feasibility.
