The simulated annealing algorithm is employed to implement the actuators placement optimization for a tensegrity structure, and the effect of actuator positioning on the vibration control of the structure is analyzed. To this end, the ANSYS model of a 4-floor tensegrity structure is built, and the state space control equation of the structure through mode transform and mode truncation is deduced. Based on optimal vibration control for the tensegrity structure, the energy of the system with respect to actuator locations is chosen as the optimal criterion. Simulation results indicate that the optimization method is effective, and that the performance of vibration control of the tensegrity structure is improved dramatically when actuators are placed in the optimal position.
