Abstract: In this paper, a method is presented for determination of actuator numbers and locations for the active vibration modal control of flexible structures. This method is based on the complex modal analysis and dynamic sensitivity analysis. It is thought that the actuator assignmentin in vibration coatrol systems should depend on natural properties of systems, but should not depend on a particular choice of initial conditions or control laws.

Key words: vibration control, modal analysis, actuator assignment, dynamic, sensitivity analysis
