Abstract：LQR control algorithm is the most widely used method in the active control of the structure. The choice of weight matrices Q and R are important to the control effect of the structure. Hence, how to determine the optimal form and size of the Q and R to obtain the global optimal control is still a difficult topic. The matrices Q and R are optimized based on genetic algorithm under objective function and the results are verified in this paper.
