Abstract: This paper presents the optimal design methodology of number and locations of actuators in active vibration control of a space truss using multiple piezoelectric ceramic stack actuators. The eigenvalue distribution of the energy correlative matrix of the control input force is applied to determine the optimal number of actuators required, and genetic algorithms (GAs) are adopted to search for the optimal locations of actuators. The results show that the disturbance acting on a structure is a key factor in determining the optimal number and locations of actuators in active structural vibration control, and a global and efficient optimization solution of multiple actuator locations can be obtained using the GAs.
