The Performance Study on Two-Stage Vibration Isolation System with Active Magnetic Suspension Control

摘要：

Two-stage vibration isolation system is normal equipment on naval vessel, which has good function of vibration isolation. Active control on vibration isolation system is better than passive control. Active magnetic suspension control has man-y virtues like alterable control methods and variable stiffness and damping. So that it is applicable to complex multi-interferes and multi-coupling floating raft. This paper set up mathematic models of two-stage vibration isolation with active magnetic suspension control system and solves the transfer functions. After simulating by MATLAB, it analysis the effectiveness of K_p , τ_d , T_i of PID controller to vibration isolation and the parameters which influence the vibration isolation performance including up and down layer stiffness, damping and mass ratio. The simulation results indicate that active magnetic suspension has good works to vibration isolation. At the same time, on the basis of these results, the structure of the systewm can be optimized.
