title = "Active vibration control of gyroelastic body with optimal placement of actuators",
abstract = "This paper studies the optimal placement of discrete actuators on the gyroelastic body based on the linear quadratic regulator (LQR) control. The dynamics of the cantilevered gyroelastic system with different installation directions of control moment gyros (CMGs) is derived. The LQR performance is considered as the objective for finding the optimal configuration of actuators. The optimal placement of actuators is formulated in the frame of combinatorial integer optimization problem. Genetic algorithms (GAs) are used to solve the combination problem of the gyroelastic body with a fixed number of actuators. The effectiveness of the optimized configurations for different cases with different installation directions of CMG actuators in active vibration suppression using LQR control is studied. Numerical results show that the cantilevered gyroelastic body with hybrid installation directions of actuators enables fast vibration suppression with less control effort when compared to the situations with the same directions of all CMG actuators.",
