Theoretical Design of a Vibration Isolation Controller with Wide Frequency Isolation Performance

In this paper, the characteristics of a two stage active vibration isolation system is analyzed theoretically. By means of deducing force transfer rate and using response of super stratum mass as input parameter, a controller with wide frequency vibration isolation performance is constructed. And theoretical analysis indicates the system has unconditional stability. Active vibration isolation simulation of a two stage system with the controller is conducted and its results show that the two stage isolation mounting with the controller constructed by the method proposed in this paper has superior vibration isolation capability even in the case that disturbance force input is in a wide range.
