Study on the Optimization of the Double-Layer Hybrid Vibration Isolation System Based on the LQR Algorithm

Abstract

The LQR algorithm has been widely used in the hybrid vibration isolation system. However, it cannot make the hybrid vibration isolation system global optimal with the coupling of structure and controller. Hence, the multi-object optimal design of the double-layer hybrid vibration isolation system based on the LQR algorithm was made by the NCGA method. The results showed that the vibration of the mechanical equipment did not get worse with the reduction of the force transmission ratio, and it made an approach to the optimal design of the hybrid vibration isolation system.
